《洞神八帝元變經》

Human affairs are often shrouded in obscurity, where the distinction between benefit and harm remains unclear. Before gains and losses become apparent, few can discern the critical junctures of safety and danger. Thus, the multitudes unknowingly tread perilous paths and stumble into hazardous situations. Such predicaments arise from the inability to foresee survival or demise, leading to these precarious states.

Both sages and ordinary people cherish life above all else; the wise and the foolish alike treasure their physical form. Therefore, the sages, valuing life, establish teachings to prevent calamities, use laws to deter wayward intentions, open paths of humility through ritual propriety, and resolve doubts through divination (bushì). Though these methods differ in form, they all serve as varied means to preserve life—supporting moral education, restraining evil, and ultimately converging toward the same end.

The essential principle of nurturing life lies foremost in avoiding harm, and the best way to avoid harm is to dispel confusion. The most effective means to dispel confusion is divination, while the foundation of divination lies in understanding the ways of spirits and deities. The workings of spirits and deities may manifest through celestial signs as auspicious omens, through terrestrial phenomena as warnings of disaster, or through human affairs as portents of fortune or misfortune. The Book of Changes states: "Those who comprehend the Dao of transformation understand the actions of the divine." The so-called "divine" can perceive past and future and bring all things to fruition. Thus, those who attain communion with the divine reach a state of unity with it—this is not merely about averting disaster or gaining wisdom.

Yet the arts of summoning and commanding spirits and deities have existed since ancient times. Figures like Dongfang Shuo (a Western Han mystic) and Yi Feng (an Eastern Han occultist) were revered as sages during the Han dynasty, while Guo Pu (styled Jingchun) was a prominent master in the Jin dynasty. Countless others dwelling in mountain forests attained supernatural abilities. However, these arts have been passed down for so long that their teachings have become fragmented and difficult to fully grasp. Even those adepts who achieved results feared that disclosure would invite calamity, so they guarded their secrets closely. Unless bound by life-and-death friendship or shared aspirations, none would reveal the truth. Only those predestined and aligned with the Dao could encounter enlightened masters and receive genuine transmission.

The texts circulating today are said to have been compiled by the monk Huizong. The spirit diagrams and medicinal records therein fill no more than three pages, with drug names altered beyond recognition—greatly diverging from the records in the Compendium of Materia Medica. In my youth, I was devoted to esoteric arts, weary of worldly life and seeking the Dao. I studied these texts tirelessly, yet their cryptic and incomplete nature made their profundity elusive. These arts are abstruse and subtle, with few achieving tangible results.

I lament that there are no close friends nearby whom I might consult, yet my pursuit of the Daoist arts has never ceased—my heart remains wholly devoted to exploring those profound and mysterious principles. In my tireless search for an enlightened teacher, I traveled far and wide seeking instruction until finally encountering a venerable master thoroughly versed in these ways. He personally transmitted oral secrets, resolved all my doubts, corrected my knowledge of medicinal ingredients and their proper usage, and meticulously taught the essential techniques: the application of talismanic incantations (fulu), the crafting of wooden templates for the Yu Steps (ritual pacing patterns), the ceremonial establishment of altars, and the various methods for verifying spiritual signs.

Now I have organized this knowledge systematically into fifteen chapters based on practical application. Those who study this art must first understand the proper sequence of cultivation and grasp its pivotal points. Therefore, I begin by outlining the main principles:

The first chapter explains how the nature of divine spirits (shen) is utterly distinct from ordinary existence—their mystery compels our reverence, hence the second chapter specifically depicts their forms and powers.

The third chapter emphasizes selecting auspicious timings for ritual practice, as all actions must align with temporal cycles.

The fourth chapter details how the Yu Steps and incantations require preparatory practice, being the most crucial techniques for summoning spirits.

The fifth chapter clarifies the efficacy of talismans (fulu) and verification methods—mastery brings swift results.

The sixth chapter warns that spoiled medicinal ingredients or impure devotion will prevent spiritual manifestations; one must prepare fresh ritual aromatics and maintain reverent sincerity.

The seventh chapter states that the practice space must be spacious and tranquil, or efficacy will be hindered.

The eighth chapter teaches that vegetarian fasting and simple attire suffice to commune with spirits, though sustained commitment is necessary for accomplishment.

The ninth chapter stresses that purity and reverence alone can summon the divine, with ritual offerings requiring immaculate cleanliness.

The tenth chapter prescribes the arrangement and varieties of sacrificial foods, as different offerings affect summoning outcomes.

The eleventh chapter cautions that omens precede a spirit's arrival—unrecognized, they may provoke terror.

The twelfth chapter warns that acquired spiritual capacities must be used judiciously, never displayed lightly.

The thirteenth chapter observes that improper command of spirits invites harm—one must master correct methods.

This scripture primarily discusses cultivation methods and precautions, organized into several key points:

Practitioners must understand how to control their heart-mind (shen), as outlined in the thirteenth principle. Those who flaunt their knowledge or reveal secrets to unworthy individuals will inevitably invite misfortune. Thus, the fourteenth principle emphasizes that only through cautious self-cultivation can one preserve life (xingming).

Ordinary people often dismiss these truths, either slandering them out of ignorance or mocking them foolishly. Therefore, the fifteenth principle advises using verified methods from past masters to guide such individuals. The author humbly states that although their understanding is limited, the text systematically organizes these teachings according to their inherent principles. The scripture's themes shine as clearly as sunlight, with elegant phrasing that forms complete chapters. While not exhaustive, it provides comprehensive guidance for those with spiritual aptitude to study.

The Dongshen Badi Yuanbian Jing (Scripture of the Eight Imperial Metamorphoses from the Divine Cavern) opens with the Yellow Emperor's account: the Southern Dipper's historical assistants include eight spirit-deities called "Imperial Celestial Envoys" who take turns descending to inspect the human realm, secretly protecting Daoist practitioners. Those who purify themselves and sincerely revere the Dao will find these deities manifesting as benevolent companions, constantly at their side to forewarn of fortune or calamity, preventing disasters before they occur and bestowing invisible blessings. Such esoteric methods are more precious than ten thousand pieces of gold—they must only be transmitted through sacred oaths to compassionate, sincere individuals who cultivate their nature (xing) while remaining detached from fame and wealth. Revealing them carelessly to vulgar people benefits neither party.

The Yellow Emperor stresses that cultivation's essence lies in purifying one's aspirations and maintaining single-minded focus. Practitioners must constantly observe their inner state with serene awareness, disciplining body and mind day and night to eliminate distracting thoughts. Disturbances cloud the heart-mind; an unclear heart-mind cannot perceive reality's essence or comprehend celestial mysteries. How could those without steadfast resolve possibly resonate with the Dao (Dao)? Those who genuinely seek the Dao without clinging to life find success as effortlessly as mountain streams pouring into valleys, while those who chase reputation without genuine practice struggle like trying to channel springwater into the clouds.

In mundane worldly affairs, even negligence and indolence will yield no results—how much more so for the profound and mysterious supreme Dao? One cannot attain it through casual effort; it demands diligent devotion.

All who cultivate the Dao must first master Yu Steps (a Daoist ritual pacing technique) and sacrificial prayers. Every essential technique must be memorized and internalized until performed with effortless fluency. Medicinal ingredients and ritual offerings must be meticulously prepared, ensuring the highest quality. The specific method is as follows: on the Gengyin day, enter the purification chamber to compound medicines and inscribe talismans (fulu); by the Gengzi day before the yin hour at dawn, enter the meditation chamber to erect the divine altar, hang and wear talismans, pace the Yu Steps, and ingest both talismans and elixirs. Only after completing these steps may one hold the ritual tablet to recite invocations, facing the altar to perform sacrifices. Scripture recitation must flow smoothly—stammering or hesitation will delay the efficacy. These are the fundamental principles of Daoist practice.

The cultivation site must be an open, purified space. The fasting courtyard and divine chamber should be immaculately clean, perfumed with incense, with all garments and utensils exquisitely pure. Demeanor and ritual decorum must be scrupulously maintained without the slightest error.

Concerning the supernatural powers of the Eight Great Spirit-Beings (attendants of the Southern Dipper Star Lord): If a cultivator sincerely seeks the Dao with pure heart-mind, excels in using talismanic medicine, and masters Yu Steps, these eight deities will descend like celestial officials to offer protection. They foreknow omens of fortune and calamity, issuing advance warnings. Each possesses unique abilities: some help avoid warfare and resolve enmities; others assist in obtaining immortality elixirs (xianyao) and realizing the Dao; some aid in gaining official promotion and wealth while dispelling slander; others enable spirit vision to recognize ghosts and demons; some transform misfortune into blessings and relieve famine; some foresee life-death transitions and transmit messages across a thousand miles; some enhance wisdom and prosperity; others ensure bountiful harvests and attract treasures; while some safeguard nocturnal travels by repelling tigers and thieves. These divine efficacies are endlessly varied beyond full description.

The first spirit-being, named "Xingwen" (Prosperity of Culture), wears light azure robes with crimson skirts. He assists in flourishing literary fortune and avoiding military disasters.

This scripture records the divine powers and characteristics of eight important Daoist deities (the Eight Emperors of Dongshen). It provides detailed descriptions of several deities' appearances and abilities:

The second deity in the Kun position (southwest in the Bagua) is named Xingcheng. He wears a round crown with three decorative bands, dressed in ancient robes with a leather belt, holding a knife in his right hand while his left hand hangs naturally. His attire consists of light red upper garments and light yellow lower skirts with green borders. This deity can obtain the elixir of immortality that grants ten thousand years of life, and can even pull out fish measuring one chi in length from underground caves for people to eat, conferring longevity. Historically, four cultivators—Zhang Yong, Su Jing, Xing Bian, and Dong Xuan—attained immortality by commanding this deity to acquire the elixir. They still live on Yangsui Mountain today, consuming grains yet having achieved eternal life.

The third deity in the Zhen position (east) is named Xingsong, dressed in green upper garments and green skirts with black borders. He can bestow generational wealth and noble titles, dispel slander, protect people from disasters, and fulfill all desires. Additionally, he ensures bountiful harvests, eliminates all misfortunes, and fulfills heartfelt wishes.

The fourth deity in the Xun position (southeast) is named Xingming, wearing light yellow upper garments and light red skirts with black borders. He possesses a unique ability: without needing to learn the Yu Steps (a Daoist ritual walking technique) or consume elixirs, simply reciting this scripture for three years enables one to see spirits directly. All manner of supernatural beings—including those inhabiting trees, water, soil, mountains, forests, doors, wells, latrines, and households, as well as animal spirits—over 240 documented types of entities can be clearly discerned in their true forms. No talismans or elixirs are required; merely reciting the scripture for three years leads to genuine attainment.

The fifth deity in the Kan position (north) is named Xing'er, clad in light red upper garments and light green skirts with black borders. He can help people avert disasters and turn danger into safety. During famines, he can also conjure food and drink, ensuring an uninterrupted supply.

The sixth deity in the Li position (south) is named Xingxu, dressed in light green upper garments and light yellow skirts with black borders. He enables cultivators to become physician-shamans who can foresee life and death. If illness strikes a household, he can accurately diagnose its severity and predict survival or demise, and can also obtain news from a thousand miles away. Moreover, he can secretly deliver gold, silver, and treasures to people's homes.

The Scripture of the Eight Thearchs' Primordial Transformations (Dongshen Badi Yuanbian Jing) primarily discusses the powers and summoning methods of eight spirit-deities, as well as the vital importance of temporal rhythms in the operation of all things.

The seventh spirit-deity in the Gen (Mountain) position is named "Xingjin" (Prosperous Advancement). He assists people in obtaining bountiful harvests and thriving sericulture, enables the discovery of rare and precious treasures, and brings all manner of good things into one's household. He can instantly produce delicacies of fish and meat, and even summon women from a thousand li away to appear immediately before the summoner. However, these arts must never be casually transmitted—they require strict secrecy and cannot be divulged even for ten thousand taels of gold. When summoning, one must wear plain robes with blue skirts and blue trimmings.

The eighth spirit-deity in the Dui (Lake) position is named "Xinggao" (Prosperous Elevation). He enables fearless nighttime travel, protection from bandits, dispels twenty-seven types of calamities, grants mastery over tigers and wolves, and allows one to outrun galloping horses. These arts demand even greater caution in their application.

These eight spirit-deities operate in complementary pairs, taking turns overseeing human affairs in three-day rotations. Those seeking their assistance must observe purification and fasting on the deity's designated day, prepare an altar with offerings at the western door pivot indoors, and invoke the deity's name—an infallible method verified by sages throughout history. These are not empty words of deception; sincere practitioners who perform the rituals with genuine devotion will witness immediate efficacy.

On the significance of temporal rhythms: The fundamental operation of heaven and earth lies in the transformations of Yin and Yang (the Daoist conception of complementary cosmic forces), which in turn are governed by the movements of sun and moon. Their revolutions create the four seasons, whose changes generate all living things. All creation follows this temporal order—a profound mystery that shapes lifeforms and sculpts all phenomena. When the moment ripens, events unfold naturally; when the season arrives, all things renew themselves. Though this temporal mechanism operates with exquisite precision, most people remain unaware of it. Only those of penetrating understanding grasp this principle and succeed by aligning with the proper timing. When celestial timing is disordered, winds and rains fall out of harmony; when earthly timing is disrupted, nothing grows properly; when human timing is misaligned, social order collapses. Thus, whether in public service or reclusion, in silence or speech, the wise always act in accordance with the proper moment.

This scripture primarily discusses the importance of selecting appropriate timing for cultivating magical arts, emphasizing the crucial nature of temporal alignment.

The ancient sage Emperor Yao taught reverent compliance with celestial timing, while Jiang Taigong (Lü Wang) warned that once an opportune moment passes, it becomes difficult to retrieve. Timing influences the movement of heaven and earth, moves spirits and deities, and determines the success of human affairs—it is the key that connects the Three Powers (heaven, earth, and humanity). Those who practice Daoist arts must follow the transformations of Yin-Yang and choose auspicious hours to perform rituals. Missing the optimal moment, even by the slightest deviation, can lead to entirely different outcomes.

The three most favorable periods for cultivation are: the first month of spring (Zhengyue), the first month of summer (April), and the mid-autumn months (August–September). Among these, spring is the most ideal season, as it marks the revival of all things. The Virtue (De) of Wood (among the Five Phases) governs benevolence, the climate is mild, and the scenery is harmonious. Practitioners may choose to cultivate in nearby gardens, open plains, or secluded sacred mountains. During this season, plants sprout, flowers bloom, and the surroundings are tranquil—even birdsong and flowing water sound particularly melodious, making it perfect for advanced practices like "riding dragons and phoenixes."

Summer is the second-best season, as fresh bird eggs (commonly used in ancient alchemical preparations) can still be obtained. Autumn and winter are the least ideal, as birds hide and medicinal ingredients become scarce. Choosing spring is not only due to its favorable climate but also because fresh cultivation materials (such as bird eggs) are most potent during this season.

This scripture primarily discusses the ritual protocols and temporal taboos for communicating with deities and refining elixirs in Daoist cultivation practices.

Regarding medicinal preparations, it emphasizes the necessity of using fresh ingredients, as spoiled or deteriorated herbs will render the practice ineffective. If collection during the optimal seasons (spring and summer) proves impossible, sun-dried herbs from autumn and winter may be used as a last resort. The text clarifies that deities truly value the practitioner's virtue (De) rather than the abundance of offerings or medicinal materials.

Requirements for purification rituals (Zhaijiao): Before entering the sacred chamber (cultivation space), practitioners typically observe forty-nine consecutive days of purification (seven times seven days). In urgent circumstances, a minimum of seven to fourteen days (one or two seven-day periods) suffices, but physical and mental purity must be maintained until the Gengzi day (a specific calendrical date) for chamber entry.

Elixir preparation procedures: On the Gengyin day, prepared ingredients are brought into the sacred chamber, where pounding and blending are completed during the Hai hour (9-11 PM), accompanied by the inscription of corresponding talismans (Fulu).

Elixir ingestion ritual: Before the Yin hour (3-5 AM) on the Gengzi day, practitioners enter the sacred chamber performing Yu steps (a Daoist ritual gait), consume talisman-infused water before taking the elixir, and conclude with ceremonial recitations. Talisman usage follows the same day as elixir preparation, hence requires no repetition.

Two types of offering times exist: morning offerings before the Yin hour, evening offerings after the Hai hour. The scripture mentions eight spirit-beings (Xingwen, Xingcheng, Xingsong, Xingming, Xing'er, Xingxu, Xingjin, Xinggao) who descend during specific periods. For instance, Xingwen and Xingcheng appear during Yin-Mao-Chen days (dawn to mid-morning), Xingsong and Xingming during Si-Wu-Wei days (late morning to afternoon), etc.

Summoning these spirits requires initiating rituals from the Gengzi day, invoking divine names within the sacred chamber. With proper observance, deities manifest within fifteen days, engaging in dialogue and obeying commands. Their appearances remain unpredictable, often occurring before Yin hour, after Hai hour, or at midnight (Zi hour).

The text concludes by emphasizing that spirit-commanding arts belong to profound esoteric practices, suitable only for reclusive cultivators pursuing longevity with purified hearts and worldly detachment. Only benevolent gentlemen upholding righteousness or devoted hermits can thereby realize the Dao (the Way), attaining not merely precognition but ultimately higher spiritual realms.

This passage primarily discusses the origins, functions, and specific methods of the "Yu Steps" (Yubu), a Daoist ritual practice.

Regarding practitioner qualifications, the scripture states: Even those with sincere devotion to the Dao who cannot fully withdraw from worldly life may practice this method. However, one must never casually reveal celestial secrets, as this may invite spirit interference or calamities. Ordinary people encountering such situations often suffer sudden misfortunes, making this practice unsuitable for general cultivation. It's best to begin study after forty years of age - younger practitioners must possess upright character, profound learning, and absolute discretion to qualify.

Traditionally attributed to the Great Yu, these ritual steps were used to summon deities. During his flood control efforts, when facing perilous situations of unfathomable depth, Yu employed this method to invoke sea gods, river deities, and mountain spirits for guidance. Observing a divine bird chanting incantations that could overturn massive stones along the southern coast, Yu imitated its movements to create the Yu Steps, which became foundational for various mystical practices.

Later figures like Prince Huainan Liu An developed the Yu Steps into over ninety variations, yet the most potent remains the original three-step, nine-trace pattern. This sequence mirrors the movement of the Big Dipper's nine stars - beginning with the left foot, three steps form nine footprints corresponding to the Li (Fire) and Kan (Water) trigrams of the Bagua.

The specific method involves: Establishing an altar indoors, facing it while using Xia dynasty measurement standards to mark a three-chi distance. Pure white ash is used to draw astral diagrams on the ground. Mastery of accompanying incantations and precise movements is essential for successful spirit summoning - the slightest error causes failure.

The scripture particularly emphasizes that among all methods for invoking spirits and perceiving ghosts, the Yu Steps remain paramount. Reference diagrams documenting their efficacy are appended, though not detailed here.

This passage describes a Daoist ritual practice called "Yu Steps" (Yubu) along with its accompanying incantations, as well as discussions about Fulu (talismanic script), the mystical written symbols used in Daoism to summon deities and expel malevolent forces.

When performing the Yu Steps, the practitioner stands at the Earth Gate (Xun position, southeast direction) facing the altar. The process begins with quiet sitting and lightly tapping the teeth fifteen times, followed by holding the breath to commence the sacred star-walking steps. The specific footwork sequence is: left foot steps on Li position (south), right foot on Kun (southwest), left foot on Zhen (east), right foot on Dui (west), then both feet join together at Dui position. Next, right foot steps on Gen (northeast), left foot on Kan (north), right foot on Qian (northwest), left foot on Heaven Gate (Qian position), right foot on Human Gate (Kun position), finally both feet stand together on the Human Gate. After completing the steps, normal breathing resumes and the incantation begins.

The incantation essentially conveys: The two primal forces of Heaven and Earth complement each other, praying for cosmic harmony. Through these sacred steps, one resonates with celestial energies, aligning the Three Powers (Heaven Gate, Earth Gate, Human Gate), subduing spirits, dispelling inauspicious forces, and fulfilling petitions. It concludes with the standard Daoist formula "Swiftly, swiftly, in accordance with the statutes of the Supreme Lord Lao" (Taishang Laojun Lüling), indicating immediate execution by the authority of the deified Laozi.

Regarding Fulu, the text explains: These talismanic scripts are celestial immortals' sacred writings for summoning divine powers, considered esoteric treasures of Daoism. They can reveal the rise and fall of nations, the fate of people, and the fortune of households. Daoist tradition holds that the patterns revealed in turtle shell divination share the same prophetic nature as Fulu—both can foretell auspicious or ominous events. Once manifested, these scripts make spiritual entities unable to conceal themselves. Daoists employ various types—spirit writings (Lingwen), true writings (Zhenwen), and ghost talismans (Guifu)—as secret techniques for commanding divine forces. Through these, practitioners can summon celestial and earthly deities, exorcise supernatural beings, attain longevity, or achieve prominent status. The efficacy of Fulu is beyond full description; here only its essential principles are briefly introduced.

The passage concludes by mentioning two specific talismans: "Qian Talisman" (northwest direction) associated with a deity surnamed Liu with the courtesy name Bosheng, and "Kun Talisman" (though the description is incomplete in the original text). These talismans are meant to be ingested for their effects.

This scripture explains the methods for drawing and positioning the "Eight Imperial Metamorphosis" talismans (Fulu) in Daoist practice. It first details the eight talismans corresponding to specific directions and deities:

The Kun talisman (representing Earth) should be hung in the southwest, associated with a deity surnamed Zhu with the courtesy name Jiangmeng. The Zhen talisman (representing Thunder) in the due east must be suspended with a pinewood cord. The Xun talisman (representing Wind) in the southeast requires the essence of bright mystery (Mingxuan Jingqi), linked to a deity surnamed Zhang with the courtesy name Lulong. The Kan talisman (representing Water) in the due north corresponds to a deity surnamed Jiao called Junzi. The Li talisman (representing Fire) in the due south is connected to a deity surnamed Feng named Maxu. The Gen talisman (representing Mountain) in the northeast is called "Jinri Yuan." The Dui talisman (representing Marsh) in the due west relates to a deity surnamed Liu with the courtesy name Mengyuan.

The Yellow Emperor (Huangdi) instructed: To summon these eight divine emissaries for commanding spirits, one must prepare on the Gengyin day (an auspicious date) during the Ren-ding hour (9-11 PM). In a purified chamber, prepare a three-inch square paulownia wood board. Apply cinnabar to the board, hold one's breath, and draw the talismans with ink. All eight talismans must be completed in a single flow of Qi (vital energy). After completion, place them in the shrine until the Gengzi day, when they should be positioned at their corresponding directions on the altar. Simultaneously, one must ingest talismans of the Eight Trigrams (Bagua) drawn with cinnabar until divine manifestations become visible.

The Yellow Emperor emphasized: These talismans constitute secret methods practiced by perfected beings (Zhenren) and immortals. If practitioners maintain sincere devotion, strictly observe precepts, and follow the scripture's instructions with purity, hanging these talismans will immediately manifest spirits that respond to thought. Prolonged cultivation may even lead to daylight ascension (bairi feisheng), transcending mere spiritual communication.

The text concludes by highlighting the crucial role of alchemical substances: The Golden Elixir (Jindan) and Jade Nectar (Yuye) are secret methods for achieving immortality, while numinous herbs (Lingzhi) are essential for nurturing life. These substances nourish the physical form and serve as sacred means for prolonging existence. The mentioned "reverted elixir" (Huandan) refers to repeatedly refined alchemical compounds, while "Jade Nectar" denotes liquid immortality elixirs.

This scripture describes several medicinal herbs with extraordinary properties and their methods of preparation. Certain herbs can summon wind and rain, cure diseases, or commune with spirits; others can repel tigers, ward off weapons, avert disasters, or prevent theft. Some enhance perception or transform one's temperament. These herbs possess such potent efficacy that their powers rival the natural forces of heaven, earth, and the four seasons—their full effects are beyond complete description.

Seven specific herbs are detailed:

The first is called "Ghost Soldiers" (also known as Ghost Arrow Grass). Only its feathery parts with attached bark are used, while roots, leaves, and stems are discarded. Found in mountainous regions, it should be gathered seasonally.

The second, "Ghost Fan" (Ghost Fan Sprout), grows commonly in mountain forests and swampy areas, requiring no elaborate explanation due to its prevalence.

The third, "Ghost Press" (Stone Press), grows where mountain streams flow over shaded rocks—a type of aquatic moss resembling ordinary varieties.

The fourth, "Ghost Sprout" (from Ghost Supervisor's Sprout), also demonstrates efficacy when used properly.

The fifth, "Ghost Mortar," employs its roots. As this is commonly recognized, no detailed description is needed.

The sixth, "True Cinnabar" (a superior variety resembling realgar), exhibits a bright, lustrous yellow hue without pungent odor, classified under the realgar category.

The seventh, "Black Eggs," must be collected from intact bird nests during the third lunar month of spring. After gathering, fifteen yolks and whites should be poured into earthenware, sun-dried, then scraped and stored wrapped in paper for autumn and winter use. When needed, soak in spring water to soften before combining with other herbs to form pills.

All these materials require season-specific harvesting and unique processing methods. Particularly for Black Eggs, sun-drying preserves them against seasonal scarcity—reconstituted only when required for use.

The Dongshen Badi Yuanbian Jing (Scripture of the Eight Emperors' Mystical Transformations) details concrete methods for preparing and using spirit-summoning elixirs. Six medicinal ingredients must be gathered—fresh and unspoiled—then carefully selected according to the scripture's requirements on the Gengyin day (a specific date in the celestial stem-branch calendar). The ingredients are to be ground in a purified fasting chamber, facing away from inauspicious directions, and mixed with bird eggs to form pill-sized pellets resembling phoenix tree seeds. The entire process must be conducted in secrecy; if witnessed by others, the ritual's efficacy will be nullified.

For ingestion, the Gengzi day (another auspicious date) before dawn is chosen, performed within a consecrated ritual space. First, talismans (fulu, Daoist apotropaic documents) are hung and worn, followed by pacing the Yubu (Daoist ritual steps). After consuming talisman-infused water and the pellets, offerings are presented. The practitioner must take the talisman water and two pellets twice daily—morning and evening—holding them in the mouth to dissolve gradually before swallowing. Swallowing them directly prevents the spirits from manifesting. Devout adherence to this method for fifteen days will cause the eight spirit-deities to materialize and converse—a technique repeatedly verified as effective.

Should one suspect the spirits of deceit, burying one pellet at the site of their initial appearance ensures summoned entities can never lie. The core of this art lies in ingesting the elixir; without it, spiritual communion remains impossible. The text cites the ancient adept Zhang Lu (founder of the Five Pecks of Rice movement in the Eastern Han), who observed that while Daoist scriptures on transcendence are numerous, some require rare, costly herbs combined with bigu (grain avoidance) to achieve immortality, whereas others permit longevity through elixirs alone with normal diet. This reflects the varied emphases of different sages' cultivation methods.

Finally, the scripture stresses that spirit-summoning rituals are best performed in secluded mountain wilderness. This passage systematically documents Daoist spirit arts—from elixir preparation and ingestion to ceremonial protocols—exemplifying the tradition's structured exploration of mystical practices.

When selecting a site for spiritual cultivation, one may seek spacious garden estates near villages to establish purification courtyards. The location must avoid proximity to households conducting funeral rites, with newly constructed buildings being most preferable. If absolutely necessary, older dwellings may be used, but sites previously contaminated by corpse storage or livestock birthing are strictly prohibited. The ground should be coated with fragrant clay to maintain purity, as defilement would compromise ritual efficacy.

The cultivation site requires perimeter walls or hedges to ensure proper separation between inner and outer spaces. The courtyard should measure approximately twenty paces square (an ancient pace being about five feet). Along the southern and western walls, reserve four paces of space to construct the sacred chamber, which must be divided into three sections: The eastern chamber (sixteen feet square) contains the practitioner's meditation mat oriented northward; the central chamber features a southern gate; the western chamber requires three gates (south, west, north) with an eight-foot square, three-inch high altar at its center. Construct this altar from white chalk mixed with aromatic herbs, pounded into a pure, fragrant platform.

East of the sacred chamber, build a ten-foot square purification room connected to the sacred chamber's southeastern corner, screened with thick curtains. Install one-foot square paper windows in the sacred chamber for illumination. North of the purification room, construct another chamber of equal size for storing ritual offerings and implements. All rooms require doorway curtains—bamboo for the sacred chamber, thatch for others.

Regarding practitioner's attire: Clothing serves both practical protection from cold and dampness, and ceremonial reverence. Worn garments foster timidity, while new robes inspire courage. Jade ornaments convey refinement, armor and spears manifest martial spirit, coarse hemp mourning clothes express grief, and kudzu headbands with straw sandals demonstrate Dao-seeking resolve. Practitioners must select appropriate attire for different occasions—this fulfills ritual requirements while aiding mental alignment during cultivation.

For practitioners (shuren) seeking communion with divine beings, the key lies in maintaining inner focus and outer restraint. When the heart is swayed by desires and thoughts chase after external objects, when internal and external states influence each other and worldly cravings intertwine, the practitioner becomes distracted during ritual practice, making it difficult to summon spiritual presences.

Those pursuing the virtuous path (De) should cherish life while holding material comforts lightly. Excessive pursuit of fine clothes and rich food breeds arrogance and dissipation, whereas simple fare nurtures the Qi of tranquility. Though clothing and food are life's necessities, Daoist cultivators must first observe precepts—even ordinary people shouldn't wear filthy garments, let alone practitioners who emphasize purity and solemnity. The essential principle is eliminating extravagance through frugality and simplicity: a coarse hemp headscarf, deerskin cap, unbleached cloth robes, or felt boots and socks all suffice. Garments need only be clean and tidy, reserving secular finery only for unavoidable long journeys.

The practice space should be arranged along the eastern wall of the divine chamber (meditation area), with felt mats and bedding spread on the floor. Eat twice daily—simple porridge with salt or rice with fruit—while maintaining slight hunger, as spiritual possession occurs more easily when the body is weak, whereas fullness obstructs divine connection. Prepare fifteen days' supply of clean water and vegetables beforehand, avoiding all taboos during this period. Withdraw from crowds and noise to preserve environmental purity.

In purification rituals (zhaijiao), cleanliness and sincerity matter most. Reverence toward spirits surpasses human courtesy; upright posture commands respect, while devout intention moves all things. Before prayer ceremonies, prepare offerings while maintaining ritual purity. When visualizing divine descent, calm the heart-mind (Xin) and eliminate distractions. Crucially: twenty-one days before the Gengyin date, enter the purification chamber for weekly fragrant-water ablutions (using spiced cleansing water). Strictly abstain from lust, meat, alcohol, pungent foods, and anger—especially avoiding idle chatter outside the chamber. Practice solitary contemplation, focusing intently on divine forms. Hundred-day observances accelerate ritual efficacy. Maintain purification from twenty-one days before Gengyin through Gengzi, with Jihai being particularly pivotal.

This passage explains the preparatory work and precautions for Daoist practitioners during specific rituals. On the Gengzi day (considered an auspicious date in Daoism), one must enter the sacred chamber (a purified space for spiritual practice) during the fourth watch (1:00-3:00 AM) to set up the altar.

Key arrangements include: All preparations must be completed before the Yin hour (3:00-5:00 AM). Offerings should be placed with solemn reverence, movements must be gentle and unhurried—sudden comings and goings or loud noises would offend the dignity of the deities. Just as drilling wood for fire requires focused speed to succeed, ritual performance demands single-minded concentration; otherwise, the effects will be delayed.

Regarding lighting in the sacred chamber: Use perilla seed oil (a plant-based oil) for lamps, maintaining ordinary brightness rather than excessive illumination. Place the lamp south of the practitioner's bed against the wall, with a wick as fine as a hairpin tip, covered by silk gauze to create soft lighting—overly bright light disturbs spirits, while excessive darkness hinders vision. Calculate oil quantity to last throughout the night; replenishing extinguished lamps mid-ritual would disrupt mental focus. Generally, dimmer lighting is preferable to excessive brightness, and extra oil should be prepared rather than risk shortage.

For offering arrangements: Different deities have specific directional placements, just as celestial mansions occupy fixed sectors—never confuse their positions. The seats for the Five Directional Deities (east, south, west, north, center) must be arranged with precise orientation. Place statues of Xingwen and Xingcheng in the east, Xingsong and Xingming in the south, Xing'er and Xingxu in the west, Xingjin and Xinggao in the north. Maintain about two chi (approximately two feet) between each deity's seat. Purify the altar space using white sandalwood incense.

The most crucial principle is sincerity's efficacy—without genuine devotion, no abundance of offerings will summon the deities. Practitioners must understand that ritual core lies in pious heart-mind and focused intention, not material offerings' quantity.

This scripture meticulously records the specifications for incense offerings and ritual objects when summoning the Eight Imperial Deities (Ba Di) in Daoist practice. It particularly emphasizes the use of Imperata cylindrica incense (also called wild thatch incense), as this is the most favored by spirits and deities—no other incense varieties are deemed suitable. This sacred herb thrives in the Jinyang mountain region, where even livestock avoid grazing upon it, marking its divine nature.

When preparing the altar, one must weave seating mats from fresh, clean Imperata grass, each mat measuring one chi square. While three-stemmed "spiritual thatch" is ideal, ordinary clean thatch suffices. These mats should be placed along the four sides of the altar—two mats per side—ensuring they don't extend beyond the altar boundaries. Maintain a two-chi gap between adjacent mats and a two-chi distance from the altar corners.

Before each deity's position, spread a yellow silk cushion measuring 1.8 chi square, orienting the divine seat to face east for receiving offerings. The ritual implements follow strict protocols:

• Two cups of wine per deity position—filled to the brim with pure, unadulterated liquor (homemade wine is preferred)
• Two pieces of dried venison jerky (1 cun square), freshly prepared, lightly roasted—beef, mutton or game may substitute if venison is unavailable
• Four Qingzhou-grown Dongyang dates from Shandong—intact, worm-free, dried yet sweet (fresh dates may be used for rituals in the seventh or eighth lunar month)
• Four roasted chestnuts from Gu'an in Youzhou (Hebei)—shelled, golden-hued, and aromatic

All offerings must be immaculately fresh and unblemished to ensure spiritual resonance. The text specifically notes that if the designated regional varieties of dates and chestnuts prove unavailable, local premium-quality substitutes may be used instead.

This scripture records a specific ritual method for summoning the Southern Dipper Star Lord (Nandou Xingjun), an important stellar deity in Daoism who governs life, death, fortune, and misfortune. The first step involves preparing ritual cakes: they must be made from freshly harvested wheat flour in clean utensils, measuring one inch in diameter, without frying in oil, and women must be excluded from the preparation process.

For the altar arrangement, seating mats should be placed in all four directions, with a ceremonial cloth laid eastward. Food offerings must strictly follow the scripture's specifications—always fresh, never reused. The practitioner must consume any withdrawn offerings, as this is believed to hasten the deity's descent. The invocation text should be written in ink on a phoenix tree wood tablet, measuring one chi (approx. 1 foot) in width and one chi two cun (approx. 1.2 feet) in length, recited once in the morning and once at night.

The invocation roughly translates as: "I, the Southern Dipper Star Lord, traverse the world to dispel calamities and wish to befriend you. From east to west, unobstructed, I shall partake of your fine offerings and bestow upon you gold and silver. Regarding hidden matters and omens of fortune or doom, I will grant you foreknowledge. Whatever your heart desires, I shall fulfill. Now, I present fine wine, fragrant dates, and other offerings—partake freely. May you descend swiftly, remaining ever by my side, inseparable as shadow and form."

Chapter 11 of the scripture describes signs of manifestation: after the ritual, various sensations may arise, appearing in dreams or waking visions. With an upright mind, the deity will manifest within fifteen days. Before the apparition, the practitioner may experience a racing heart, alternating chills and fever, or bristling body hair.

Upon first encountering the deity, only a host-guest greeting is required—no prostration. Initially, the deity’s form appears indistinct but gradually clarifies. Remain silent and maintain ritual focus until the image fully materializes. Once complete, silently pose questions, and the deity will announce its name. Thereafter, the deity will remain nearby, though one must remember the distinction between human and spirit. At first encounter, the deity may appear awe-inspiring or fearsome—maintain courage and composure, and a sense of ease will follow.

This scripture discusses the precautions practitioners should take after attaining spiritual powers. When first gaining these extraordinary abilities, adepts often become intoxicated by the novel experience—able to foresee events and resolve perplexities—but must practice self-restraint to avoid excessive indulgence that could lead to qi deviation (zuohuorumo).

Upon obtaining such powers, one must undergo a seven-day retreat in the divine chamber (shenshi, a dedicated meditation space), focusing entirely on ceremonial offerings to the deities. If urgent matters require leaving during this period, one must first petition the spirits. Even when outside, maintain gentle speech and composed demeanor, never startling the divine beings. Just as taming hawks or horses demands patience, guiding spiritual forces requires even greater reverence.

The text specifically warns that during the first hundred days after powers manifest, practitioners often experience mental distraction, giving rise to various delusions: craving wealth, chasing fame, desiring official rank, or wishing to abandon worldly life. At such times, one must forcefully restrain these impulses and never act on the temptations presented by spiritual forces—disaster will surely follow otherwise. Only after this hundred-day period can mental clarity be restored.

Finally, the scripture cautions against frivolously displaying these powers or casually predicting fortunes, especially before rulers and nobility. Such behavior not only contradicts the original purpose of cultivation but risks being labeled "heterodox practice" (zuodao, left-hand path). True gentlemen of practice should maintain propriety, keeping their abilities concealed—only then can the purity of spiritual powers be preserved long-term.

This scripture primarily discusses the taboos and proper methods for practitioners to communicate with spirits and deities. Since ancient times, some individuals who received divine revelations carelessly disclosed celestial secrets, thereby incurring misfortunes. Those who truly understand how to befriend spirits will selectively verify only a few omens and transmit methods with utmost caution—only then can they avoid calamities and preserve themselves.

The cultivation methods are divided into simplified and complete versions. The simplified version doesn't require ingesting elixirs; one need only follow specific steps: first perform Yu Steps (a Daoist walking ritual), then place medicinal pellets beneath the hair knot, in the ears, and nostrils, followed by applying them to the teeth, lips, eyes, and navel. After fourteen consecutive days of ritual offerings, deities will manifest—though their forms may appear indistinct, one can discern auspicious or inauspicious signs. With the complete elixir-ingestion method, results are guaranteed within fifteen days, granting nearly omnipotent abilities.

However, the scripture sternly warns that practitioners who flaunt their skills recklessly, act arrogantly, or abuse these methods for personal survival will instead invite disaster. True adepts perceive worldly affairs yet remain silent, foresee crises without divulging celestial secrets, seeking only their own health and tranquility. Only such individuals can eternally avoid violent calamities and ultimately attain immortality, gaining longevity and prosperity. Yet genuine Daoist practitioners should embody serenity and wuwei (non-action), distancing themselves from worldly fame and wealth—these techniques are merely expedient means to guide beginners.

Finally, the Yellow Emperor points out that although humans and spirits can communicate, their natures differ fundamentally. Deities can foretell fortunes, while mortals require special methods to establish contact. Sages, with their transparent minds, need no external aids, but ordinary cultivators and scholars of wisdom must still study these arts to explore subtle truths, using them to benefit beings and achieve immortality. The scripture emphasizes that these techniques were originally established as expedient means to guide worldly people toward the Dao.

The Dongshen Badi Yuanbian Jing (Scripture of the Primordial Transformations of the Eight Emperors of the Divine Cavern) expounds on the principles governing human interactions with spirits and deities. While ordinary eyes perceive only the limited material world, sages transmit these esoteric teachings through texts so cultivators may foresee events and navigate fortune wisely.

Humans and spirits exist in different dimensions of reality—just as discord between father and son invites misfortune, or suspicion between ruler and minister leads to bloodshed, it is profoundly delicate for mortals with physical forms to command formless spirits. The core principle lies in treating summoned spirits as brothers or companions, maintaining lifelong reverence without negligence. Disrespect may provoke divine wrath, even inviting retribution through violent calamities.

Yet one must also avoid excessive appeasement or blind obedience to spiritual directives. Overindulgence breeds arrogance in spirits, who may then belittle humans and ultimately bring disaster. When coexisting with spirits, never commit evil deeds in their name—whether murder, licentiousness, fraud, theft, or using spirits to intimidate others. Such defilements rupture the human-divine relationship.

Mediums often undergo alarming personality shifts: some turn violent, others succumb to lust or insatiable greed. These distortions reflect the differing natures of the spirits invoked. Maintain sober discernment—uncritical submission to spiritual voices disrupts human ethics and invites calamity through aberrant behavior.

At their core, spirits desire widespread dissemination of omens to validate their existence. True wisdom lies in steadfast integrity and sincerity, which naturally attract blessings and harmonious outcomes.

This scripture discusses how to interact with deities and the precautions for employing spirits, with the core principle being "caution and restraint." Although deities may manifest their efficacy through humans, if one boasts about these supernatural abilities everywhere, it will inevitably invite misfortune—just as a shadow follows the body or an echo responds to sound.

Spirits inherently desire humans to spread their miraculous deeds to demonstrate their power. However, if one excessively publicizes them, the spirits may instead begin to disturb you—causing excessive drinking, mental confusion, or erratic behavior. The correct approach is to remain silent and patient, only discreetly conveying divine revelations to the closest and most trustworthy individuals through divination (turtle shells and yarrow stalks), dream interpretation, observing Qi (vital energy) patterns, or medical arts. This satisfies the spirits’ wish to be acknowledged, benefits people practically, and avoids calamity.

When employing spirits, one must be mindful: do not trouble deities with trivial matters for divination, as this constitutes an abuse of divine power; nor should one inquire about matters that can be resolved by human effort, as this is called "burdening the spirits." If deities are displeased, they will bring misfortune. Only by approaching them with reverence and inquiring about truly important matters will one receive assistance.

The overarching principle is this: before employing spirits, one must first cultivate their own body and mind, maintaining an attitude of reverence, caution, sincerity, and benevolence. Neither arrogance nor excessive familiarity is appropriate—communication with deities should be subtle and restrained. Most crucially, secrecy must be strictly maintained, as any leak will immediately invite disaster. Thus, the sages say, "Regretting afterward is not as good as preventing beforehand"—this is indeed the ultimate truth.

The Yellow Emperor said: The most essential method for sages to preserve life lies in understanding the relationship between body and mind. The greatest distinction between benefit and harm for body and mind manifests in the differentiation between good and evil. The root of good and evil originates in mental activity—when thoughts persistently attach to external phenomena (grasping at worldly matters), discrimination arises. The objects of attachment are called "realms," while the subject that attaches is called "mind."

All phenomena in the world arise from mental activity. Actions stemming from thoughts are called "karma." The manifestation of karma is good and evil—indulging desires constitutes evil, while restraining greed constitutes good. Practicing good benefits the world and liberates one from worldly dust, while committing evil inevitably corrupts De (Virtue) and defiles the heart-mind. Therefore, sages understand that though the mind is formless, it governs all things. The physical body does not operate autonomously but relies on mental activity for movement. Yet without the body as its vessel, the mind cannot manifest its function; without the mind as its guide, the body perishes. Thus, though body and mind are distinct, they cooperate to accomplish countless virtuous deeds, ultimately returning to the Dao (the Way).

Ordinary people's minds remain impure, constantly chasing external phenomena; their bodily desires know no bounds, and their actions never cease. The mind is the root of transformation between ordinary and sage states, while the body is the vessel where suffering and joy accumulate. Sages know that calamities arise from mental activity and faults originate in the physical self. Therefore, they purify their minds to eliminate calamities and refine their aspirations to dissolve transgressions. Worldly people do the opposite—indulging passions without realizing desires emerge from within, behaving arrogantly without recognizing pride stems from themselves, recklessly pursuing violence without regard for bodily safety, ultimately inviting disaster without awareness.

Thus, sages established teachings out of compassion for ignorant beings: Through Daoist practice, people calm their minds and sever the roots of affliction; through ritual propriety, they restrain their bodies and curb desires. Ritual propriety governs worldly conduct, while the Daoist path transcends worldly dust. Though both teachings can deliver beings, without comprehending the truth of "returning to emptiness," it remains difficult to foresee fortune and misfortune. Therefore, secret arts (such as methods for summoning and commanding spirits) are transmitted to help people anticipate life and death, benefit and harm—avoiding danger to choose safety, ultimately achieving the Daoist path.

Those with lofty aspirations revere the Dao (the Way) to seek longevity; those who prefer tranquility purify their Shen (spirit) to pacify affairs. Without genuine inner realization, even mastering incantations and methods—how could one command spirits or preserve life? The above briefly explains the essentials of self-cultivation.

Special reminder: Commanding spirits is extremely difficult—one must maintain purity and caution while minimizing social engagements.

This scripture primarily discusses the taboos and consequences of employing magical arts to command spirits and deities, citing several historical figures as illustrative examples.

Regarding the prohibitions of commanding spirits and deities: One must never reveal such arts to emperors, generals, or high-ranking officials, as disclosure inevitably invites death. Those capable of commanding spirits and deities must never divulge this ability to others throughout their lives—not even to their own fathers and sons, let alone common people. Careless revelation will immediately bring fatal retribution. This warning must be constantly borne in mind.

The text particularly emphasizes that those who wield such powers must not abuse them for wrongdoing—such as exploiting divine authority to intimidate and extort, taking advantage of others' misfortunes for personal gain, or employing deceitful schemes to manipulate people. Such evils are too numerous to recount. These individuals will swiftly face divine retribution, as the deities will surely mete out severe punishment. Hence, one must remain vigilant in all actions.

The scripture then provides several historical examples:

Ji Kang (courtesy name Shuye), a renowned scholar of the Western Jin dynasty and one of the famous "Seven Sages of the Bamboo Grove," was well-versed in the classics and widely read, having authored treatises on nurturing life (yangsheng) and excelling in poetry. He was particularly adept in Huang-Lao teachings (Daoist thought) and esoteric texts. After three years of studying this art, he could summon eight deities to manifest and command them to foretell the future. The deities also imparted to him the famous zither composition "Guangling San." Notably, Ji Kang neither practiced Yu Steps (a Daoist ritual walking technique) nor consumed elixirs—he achieved his abilities solely through textual study.

Another case is the monk Huizong, whose origins are unknown but who was deeply fascinated by these arts. While cultivating atop Mount Zhongyue, before completing the prescribed period of practice, he could already perceive and command the deities.

The scripture concludes by mentioning Dong Zhongshu (a Han dynasty Confucian scholar) who could make shamans spontaneously combust, Guo Linzong (an Eastern Han scholar) renowned for his discernment of character, Fotudeng who prophesied the fall of the Zhao state, and Dao'an who predicted the defeat of the Qin state—asserting that all these feats were accomplished through the same arts. Without such methods, they would have been no different from ordinary people.

Ordinary practitioners often approach these esoteric arts with fear and doubt, for spirits and deities are not entities commonly perceived by human senses. People yearn to comprehend divine mysteries yet dread supernatural disturbances—this psychological conflict renders even willing believers incapable of true mastery. Thus many seekers of profound truths find themselves trapped in cognitive dilemmas: though they may gain superficial reputations for avoiding harm, they fail to truly escape calamity; though they harbor aspirations for longevity, they never grasp its essence. All this stems from worldly distractions and excessive self-protection.

I have long lamented this situation. Therefore, I've compiled verified methods from past masters into this text, hoping to aid sincere seekers devoted to Daoist cultivation.

In the first year of Yongping era (508 CE) of the Wei dynasty, three practitioners—Liu Zhu, Gao Rongzu, and Yan Etou—cultivated the Dao for seven years in the Western Mountains of Youzhou. During heavy snowfall (accumulating over a foot deep), a transcendent being calling himself "Daoist Huyan" appeared. He imparted distinct arts to each: teaching Gao Rongzu the "Method of Celestial Preparation," instructing Yan Etou in "Ghost Subjugation," and granting Liu Zhu the ability to command eight divine spirits. Later, Liu Zhu assisted Zhu Tianzhu in establishing a regime ("participating in military-strategic decisions"), and was appointed Minister then Governor of Youzhou. Liu transmitted the arts to Yue Chongxin, who passed them to Wang Xu of Yanmen, then to Jing Zhe of Yongtai Temple, then to Monk Ru, and finally to Liu Huizu—who preserved the complete oral formulas now recorded here to prevent their loss.

Historical transmissions to sincere practitioners—including famed adepts like Zuo Ci (style Yuanfang), Zheng Yin (style Siyuan), Ge Hong (style Zhichuan), Guo Pu (style Jingchun), and Bu Yu—have proven consistently effective.

This text documents secret diagrams, incantations for summoning transcendents, and scripture-verification methods. Special attention must be paid to the "Eastern Well Purification" days—critical moments for spirit summoning—as success is impossible without proper preparation.

Auspicious dates (lunar calendar) and corresponding two-hour periods (时辰 shichen):

• 10th night, 1st month: 9-11pm (Hai)
• 8th night, 2nd month: 7-9pm (Xu)
• 6th afternoon, 3rd month: 5-7pm (You)
• 4th afternoon, 4th month: 3-5pm (Shen)
• 1st afternoon, 5th month: 1-3pm (Wei)
• 27th noon, 6th month: 11am-1pm (Wu)
• 27th morning, 7th month: 9-11am (Si)
• 22nd morning, 8th month: 7-9am (Chen)
• 20th dawn, 9th month: 5-7am (Mao)
• 18th predawn, 10th month: 3-5am (Yin)
• 15th late night, 11th month: 1-3am (Chou)
• 12th midnight, 12th month: 11pm-1am (Zi)

These times align with the celestial "Eastern Well" constellation's (one of the 28 lunar mansions) disappearance. Purification rituals performed during these windows enable successful spirit summoning.

This passage discusses an esoteric cultivation method recorded in the Scripture of the Primordial Transformations of the Eight Emperors from the Cavern of Spirit (Dongshen Badi Yuanbian Jing). Those who master this method can freely summon and command divine beings at will. By selecting auspicious days for ritual purification baths and fasting (Zhaijiao, the Daoist purification ritual before cultivation), every divine summoning will prove efficacious.

Practicing this method also enables one to attain wealth and nobility, facilitating regular communion with celestial immortals and sages (referring to the state of achieving communication with the celestial realm through cultivation). It prolongs life and preserves health. In essence, this is a vital method of using Dao-Qi (the primordial cosmic energy in Daoist thought) to nourish the primordial Shen (one's innate spiritual nature), thereby realizing longevity and enduring presence in the world.

The scripture particularly emphasizes that such precious cultivation secrets must be strictly guarded and never casually disclosed. This reflects the Daoist tradition of "not lightly transmitting secret methods," holding that profound cultivation techniques must be selectively taught to avoid misuse or misunderstanding.
