《洞真黃書》

The Dongzhen Huangshu (Scripture of Perfect Truth: Yellow Book) comprises ten volumes. This text documents the patterns of celestial and terrestrial movements, eight procreative principles, and the correspondences between the six directions of space (heaven-earth and four cardinal directions) and the human body.

Regarding cultivation methods for men and women: Male practitioners should follow the three celestial stems of Jiazi, Jiachen, and Jiayin, ultimately returning to the Guihai period to achieve the threefold harmony of De (Virtue). Partners must coordinate their practice according to the eight procreative principles as fundamental guidelines. The text mentions that Huangshu cultivation involves eight types of primordial Qi, corresponding to twenty-four divine beings—among which three principal deities hold supreme status—accessed through the "Three-in-One Qi" (the unified essence of Jing, Qi, and Shen) to resonate with cosmic energies.

Couples may attain spiritual realization through the union of their vital essences. Specific timing for practice: The first day of each lunar month is optimal during the Yin periods of Guichou and Guimao, when Yin energy emerges and the balance between Yin-Yang is equal—this facilitates overcoming calamities and curing illnesses. The Qi of this period connects with the generative energy of Laozi (the Daoist patriarch), but practitioners must observe the "Nine-One Rule" (nine practice sessions followed by one rest period) and avoid reckless actions. The Jiachen period on the second day marks heaven and earth's generation of Yang energy; the third day's Yisi period offers the best Yin-Yang harmony; while the fourth day's Bingwu period commemorates Laozi's daylight ascension—an auspicious time for four-Qi cultivation when partners achieve threefold resonance.

Female practitioners should follow the periods of Jiawu, Jiashen, and Jiaxu, ultimately returning to Guisi. These periods correlate with the twelve earthly branches and twenty-four solar terms. Male Qi manifests as white, female as yellow; in practice, men adopt the numerical value of one, women two, while the left direction corresponds to three and the right to six. The cultivation sequence begins from Jiayin and Guichou, concluding on Guiyou day. Men practice three cycles—first during Guimao, then returning to Jiachen and Yisi—when Qi enters through the Heavenly Gate and exits via the Earthly Door, with terrestrial energy supporting the "Celestial Pillar" (the spinal column), embodying the authentic cultivation path.

Practice must endure the trial of Wuji (the central earth position of the Lofty Palace) to consolidate primordial Qi. Those seeking longevity through cultivation must complete the "Three-Five" stages (refining the three Dantian and five Qi types), but never exceed the "Seven-Nine" cycle (a specific practice period). The text meticulously details Qi quantities for various periods: Guihai corresponds to twenty-five Qi, Guisi to sixty-four, Guimao to eighty-one, etc.

Finally, the text's transmission history: Celestial Master Zhang (Tianshi) received the eight-volume Huangshu from Laozi in 142 CE (the first year of Han'an era), including three red Qi, nine and seven talismanic formulae (Fulu), along with practices like the Mystic Register (Xuanlu), Primordial Unity (Huncheng), Central Chapter (Zhongzhang), and Three Spirit Registers (Shenlu). At noon during the Yisi period on the twenty-fourth day, the complete twenty-four volumes were transmitted. Recipients underwent rigorous selection—their bone structure, virtue, and even life pledges were examined. Two volumes concerning divine beings were particularly restricted, containing profound knowledge of six Jia cycles, Five Phases (Wuxing), twenty-four solar terms, nine palaces, and eight trigrams (Bagua).

This scripture primarily elucidates the generative and controlling relationships of Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water), along with the correspondences of the Eight Trigrams (Bagua) within the Three Realms of heaven, earth, and humanity. Here's a modern interpretation:

First, it describes the marital pairings based on the Five Phases:

• The eastern directions Jia and Yi belong to Wood, while western Geng and Xin belong to Metal (Metal controls Wood). Thus, Jia "marries off" his younger sister Yi to Geng, forming the Geng-Yi couple.
• The southern Bing and Ding belong to Fire, while northern Ren and Gui belong to Water (Water controls Fire). Hence, Bing "marries off" his younger sister Ding to Ren, creating the Ren-Ding couple.
• The central Wu and Ji belong to Earth, while eastern Jia and Yi belong to Wood (Wood controls Earth). Therefore, Wu "marries off" his younger sister Ji to Jia, forming the Jia-Ji couple.
• The western Geng and Xin belong to Metal, while southern Bing and Ding belong to Fire (Fire controls Metal). Consequently, Geng "marries off" his younger sister Xin to Bing, establishing the Bing-Xin couple.

Next, it explains seasonal transformations of the Five Phases:

• When Wood flourishes in the eastern spring, Metal comes to control it (hence elm seeds fall).
• When Fire thrives in the southern summer, Water arrives to extinguish it (thus buckwheat is harvested).
• When Metal dominates in the western autumn, Fire melts it (allowing metal to be cast into tools).
• When Water reigns in the northern winter, Earth restrains it (as all things stir beneath the Yellow Springs at winter solstice).

The text then details the Three Realms correspondences of the Eight Trigrams:

In heaven:

• Qian (Heaven) corresponds to the Tianyi star, Kun (Earth) to the Sheti star
• Zhen (Thunder) to the Fenglong star, Xun (Wind) to the Zhaoyao star
• Kan (Water) to the Xianchi star, Li (Fire) to the Xuanyuan star
• Gen (Mountain) to the Xingshi star, Dui (Lake) to the Chengshi star

On earth:

• Qian manifests as metal and stone, Kun as soil
• Zhen as trees, Xun as grass
• Kan as water, Li as fire
• Gen as mountains, Dui as marshes

In the human body:

• Qian represents the head, Kun the abdomen
• Zhen the feet, Li the eyes
• Xun the nose/thighs, Gen the hands
• Kan the ears, Dui the mouth

Finally, it mentions that the Eight Trigrams originally evolved from the numerical foundation of "nine." Through these patterns of Five Phase interactions and trigram correspondences, the scripture reveals the Daoist cosmological framework for understanding universal principles.

The Dongzhen Huangshu (Scripture of the Yellow Book of the Cavern of Perfection) presents a Daoist ritual method involving the arrangement of the Nine Palaces and the cyclical movement of Yin-Yang and the Five Phases (Wuxing). Here is a simplified interpretation:

The Nine Palaces Arrangement

Nine divination rods (ancient counting tools) are placed in five directions: north (Zi), south (Wu), east (Mao), west (You), and the center—totaling forty-five rods. Following the principles of mutual generation and restraint among the Five Phases, invocations are made: Water (Shui) returns to the northern position (Zi), Wood (Mu) to the east (Mao), Metal (Jin) and Fire (Huo) each to their respective positions, while Earth (Tu) is distributed across the four seasonal directions. This forms the Nine Palaces pattern: "Nine above, one below; three on the left, seven on the right; two and four as shoulders, six and eight as feet, with five residing in the center."

The Movement of Yin-Yang

This section details the positioning of the Eight Trigrams (Bagua—Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui) within the Nine Palaces. For example, the Celestial Gate (Qian in the northwest) corresponds to the number one, while the Earthly Door (Xun in the southeast) corresponds to four. It emphasizes the proper alignment of Yin and Yang and the cyclical interactions of the Five Phases.

Temporal Calculations

The first nine days of each month follow a numerical progression from one-nine to nine-nine (i.e., 1×9=9 to 9×9=81). From the tenth day onward, the sequence shifts to the pattern of "three, five, seven, nine." A special warning is given against performing rain-summoning rituals during this period, as doing so may invite calamity.

Ritual Prohibitions

From the sixteenth to the twenty-third day, the sequence follows the "eight-eight" to "one-eight" pattern. During this time, a single rain-summoning ritual may be conducted, as it aligns with the natural harmony of Heaven and Earth's Yin-Yang union. Other days—especially those associated with the Earth phases of Wu and Ji—require caution and stillness.

Conclusion

The text underscores the unified principles of the Eight Trigrams, Nine Palaces, the sixty Jiazi cycles, and the pairing of Yin-Yang. It references the Three Origins (Shangyuan, Zhongyuan, Xiayuan) and highlights the central importance of "nine-one" (the Nine Palaces and the Supreme Ultimate, Taiji).

Overall, this scripture transmits a Daoist cultivation method integrating temporal calculations, spatial arrangements, and the cyclical movement of the Five Phases, incorporating unique numerical symbolism and directional concepts central to Daoist practice.

This scripture elucidates the principles of Yin-Yang energy circulation and cultivation taboos in Daoist practice:

Between heaven and earth exist cyclical patterns of eight winds and twenty-four rains (referring to natural energy cycles). Practitioners should observe:

• Every ten days, wind Qi (energy currents) descend
• Through embryonic respiration (a breathing technique), one may absorb twelve hundred cycles of Qi
• On the sixteenth day, three streams of Qi descend like rain
• On the twenty-fourth day, wind Qi completes its cycle

The text meticulously records Qi numerical patterns according to celestial stems and earthly branches:

• Jiazi days contain five Qi, Jiashen days six Qi, Jiawu days eight Qi, etc.
• During Guiyou and Guimao days, practitioners must observe the waxing and waning of Yin-Yang Qi

Key cultivation principles:

1. Understand the harmonizing patterns of Yin-Yang within the six directions (heaven-earth and four cardinal directions)

2. Observe taboos corresponding to numerical sequences like three-five and seven-nine

3. The human body contains three Qi on the left and six Qi on the right, corresponding to the twenty-four Shen (divine spirits within the body)

4. Vital cultivation focuses on five Qi for health preservation, while mishandling seven or nine Qi may cause illness

Cultivation methods:

• Begin practice from Renwu and Guiwei days
• Through excessive cultivation of red Qi (crimson energy), one may attain celestial ascension
• Special postures include "inverted dragon" (a unique body position) and raising hands above the head
• Untie sixteen energy knots within the body while visualizing eight Qi streams

Essential guidelines:

• Male and female practitioners must follow the regulations of the "Mysterious Register" (cultivation manual)
• Avoid reckless use of incantations and talismans
• Cultivation requires benevolent intention and reverence for life
• Paternal energy originates from the Supreme Mysterious Palace (upper Dantian), maternal energy from the Supreme Subtle Palace (lower Dantian)

This scripture integrates astronomical calendrics, Yin-Yang and Five Phases theory with essential cultivation techniques, emphasizing health preservation and spiritual practice in accordance with natural laws.

This scripture elucidates the Daoist cultivation method known as "Three-Five-Seven-Nine," which primarily concerns the circulation of primordial Qi within the body and its harmonization with the Yin-Yang forces of heaven and earth:

Before the separation of heaven and earth, the interaction of yellow and white energies generated eighty-one types of primordial Qi. In practice, adepts must attend to the Qi circulation along three pathways (left as the Upper Origin, right as the Mysterious Elder, and center as the Supreme Venerable), following the "first two then three" sequence to balance Yin-Yang.

Practitioners should, from the first to the ninth day of each lunar month, meditate on the movement of the Three Original Qi (Mysterious, Primordial, and Beginning) within the head. The human body contains twenty-four body deities (spiritual guardians of the five viscera and six bowels) whose activities must align with the numerical patterns of three-five-seven-nine. The specific method involves:

• Maintaining awareness during waking hours as "life" and during sleep as "death"
• Preserving the integrity of primordial Qi
• Following the three-five-seven-nine sequence to dispel calamities

During the middle ten days of the month (10th to 15th), special attention must be paid to:

• The convergence of the Three Powers (heaven-earth-human)
• The necessity of clear sunlight and moonlight (rain being inauspicious)
• Violating these principles being as perilous as fish out of water or humans deprived of Qi

From the 16th onward, the second half-month practice begins:

• The "eight-eight" method may be appropriately employed
• During the waning moon (approximately 22nd-28th), focus on the central earth positions (Wu-Ji)
• Even incomplete practice should maintain resonance with the twenty-four body deities

Essential techniques include:

• "Three-Ones" referring to the upright Qi of the Three Officials (upper, middle, and lower Dantian)
• Assuming specific reclining postures: feet apart with deep, elongated breathing
• Simultaneous visualization of upper/lower Dantian, twenty-four Qi currents, and the Three-Five deities
• Gender-specific directional practice: left for men, right for women

The text concludes by emphasizing:

• Aligning practice with the twelve months' Yin-Yang transformations
• Cultivating the ascent/descent of Mysterious Qi (prenatal energy) and Beginning Qi (primordial source)
• The need for discretion in transmitting these secret methods, selecting only suitable recipients

(Note: The "Three-Five-Seven-Nine" system represents key Daoist numerical cosmology—"three" denoting heaven-earth-human, "five" the Five Phases, "seven" the celestial luminaries, and "nine" the nine palaces. The "twenty-four deities" refer to the guardian spirits of bodily regions.)

This scripture expounds Daoist methods for dispelling calamities and curing illnesses through focused meditation on specific divine names combined with breath cultivation practices. The core teachings can be understood as follows:

To transcend illness and misfortune, one must receive the "True Four-Character Divine Names" (referring to specific four-character deity titles) and practice the "Eight-Character Qi Alignment" (an eight-character breathing technique). Through profound meditative states, the Three-Five Qi (representing harmonized yin-yang life force) circulates properly within the body, enabling attainment of immortal realms where body and mind attain perfect tranquility, preserving one's essential nature and vitality.

Practices differ by gender: men cultivate Three Qi and Twelve Qi, while women cultivate Five Qi and Twelve Qi, each aligned with the twelve two-hour periods of the traditional day to stabilize their spirit. Guardian deities are mentioned, including male deities Wang Wenqing and Zhou Zuoyousong, and female deities Wei Shangqing and Zhou Shigong. With clear-minded observance of precepts, efficacy is assured.

To overcome five types of calamities and eliminate pestilential diseases, practitioners should first visualize deities corresponding to the jiazi day (traditional calendrical cycle). Each day connects to different deities who can help absolve punishments from the Celestial Administration (heavenly bureaucracy) and the Three Officials (heaven-earth-water judges). The text details the rotation system of yin-yang deities: yang deities oversee yin domains for five days while yin deities oversee yang domains for five days, working in mutual coordination. For instance, on jiazi days visualize the Six Rong Ten Deities, on jiawu days the Nine Yi Ten Deities—all will actively assist practitioners.

Special emphasis is placed on understanding the mysteries of the "Six Gui" (Heavenly Stems-Earthly Branches terminology) to ensure smooth progress. Both genders must safeguard their primordial spirit (Yuanshen), maintaining proper qi circulation without disorder. The "Way of Immortality" is referenced as requiring deep contemplation.

Preparation is essential: first visualize the jiazi cycle deities, then the Twenty-Four Deities (possibly representing the twenty-four solar terms). From the first to twelfth lunar months, male and female deities' qi interconnects. Missing any element jeopardizes life preservation. Monthly deity arrangements must follow proper sequence—if deities are summoned by others, their power becomes unavailable.

When treating epidemics, practitioners should personally petition the Three Officials (heaven, earth, water) and coordinate with solar deities. The practitioner Wang Jia (generic term for cultivators) receiving these true words must study their essence with an enlightened master. The text concludes by noting these teachings were transmitted by Lord Lao (the deified Laozi) to Zhang Ling (founder of Daoism) at noon on the seventh day of the seventh lunar month during the Han'an era (142 CE), forming essential longevity instructions.

This scripture records a crucial transmission in early Daoism. The main content describes how Zhang Daoling (founder of Daoism) imparted the secret methods of the Yellow Book to disciples including Zhao Sheng, Wang Chang, Wang Zhi, and Wang Ying at noon on the seventh day of the first lunar month in the Guiwei year. The text contains several key elements:

First, regarding cultivation methods, it mentions understanding the guardian deities of male and female practitioners through the "Nine Palaces Taboos." Cultivation must align with principles like the Six Harmonies of Heaven and Earth and the Three-Five Proper Practices while regulating breath (Qi). It particularly emphasizes that practitioners must preserve their vital spirit (Shen) from birth, caring for it as one would protect their brain marrow and bones.

Second are the transmission protocols. The scripture repeatedly warns that these secret methods must be taught with extreme caution and never casually disclosed. It outlines a complete transmission system including the Three Officials (Heaven, Earth, and Water), the Twenty-Four Ruling Deities, and the "Three Masters" system comprising the Celestial Master (Tianshi), Female Master, and Lineage Master.

Next come specific cultivation techniques. Practitioners must comprehend the "Three Qi" (primordial energies of the Great Scarlet Heaven, Pure Subtlety Heaven, and Yu's Abundance Heaven) and the "Three-Five" cultivation method to transcend calamities and dispel illnesses. Male and female practitioners each have twenty-four energy channels requiring regulation.

Finally, there are temporal markers. The text identifies the Jia-Chen and Gui-Mao years as critical periods for cultivation, while noon on the seventh day of the first lunar month in the Jia-Wu year is designated as the auspicious time for scripture transmission. It stresses unwavering devotion to the Dao (Dao) during practice, warning against frequently altering methods.

This scripture reflects the rigorous and systematic nature of early Daoist cultivation transmission, incorporating essential elements like breath regulation, spirit visualization, and timing selection. It stands as an important document for studying early Daoist thought.
