General Preface to the Zhigui Collection (Part 2)

Written by Wu Wu, the Hermit of Gaogai Mountain

The preface states: Between Heaven and Earth operates the natural order, and all things possess their inherent principles. If one cannot even comprehend the fundamental laws governing phenomena, how could they possibly apprehend the great Dao? The path to immortality is profoundly mysterious, requiring the gradual accumulation of virtuous deeds and merit to achieve. A human lifespan spans a hundred years, yet few live to seventy. Even with diligent practice, how much merit can truly be accumulated? Therefore, those who seek celestial immortality must first pursue longevity, thereby gaining sufficient time to amass virtue. This gave rise to the theory of Waidan (external alchemy) transformation—attaining longevity through elixir refinement.

Yet when illness strikes, the talismanic and alchemical methods of Waidan often prove ineffective, leading to the emergence of Neidan (internal alchemy) cultivation techniques. From ancient times to the present, while many have practiced Neidan, none who achieved ascension did so without also cultivating Waidan. What is called Neidan practice essentially involves harmonizing the heart and kidneys, circulating Jing (essence) and Qi (vital energy), concentrating the Shen (spirit) through visualization, and regulating breath—or focusing on bedroom arts (an ancient health practice), gathering solar and lunar essences, consuming herbal concoctions, or practicing grain abstention and desire restriction. These are all methods for pursuing health and longevity. Among them, only the practice of "preserving the spirit and restraining breath," if perfected to the point of forgetting all distractions, somewhat resembles Buddhist meditation. Even if successfully cultivated, it belongs to the achievement of the Yin-spirit (a spiritual elevation) and ultimately requires continuous refinement.

The ancients used symbols such as Yin-Yang, the Bagua (Eight Trigrams), the Four Symbols, the Five Phases (Wood, Fire, Earth, Metal, Water), mercury and lead, and dragon and tiger (all alchemical terms) to elucidate the Dao of elixirs. This was because the sages were reluctant to reveal celestial secrets directly, instead employing these metaphors to allude to Waidan practice. Thus, an ancient song states, "The inner medicine is still the same as the outer medicine," a profound truth with far-reaching implications. Regrettably, later generations failed to probe the ancients' true intent, ignorant of natural principles, and mistook minor heterodox techniques as sufficient for immortality through Neidan alone. Have they not considered: if Neidan were truly so miraculous, why would the ancient immortals have bothered with Waidan? Today, the renowned grotto-heavens and blessed lands (sacred Daoist cultivation sites) all preserve furnace remnants where the ancients refined elixirs and ascended. If it were necessary to first achieve Neidan before using Waidan for transformation, how then do the classics record instances where even servants, chickens, and dogs ascended together with the immortals? Could these animals have first perfected Neidan?

There are also those who scour the land for numinous herbs or refine metal and mineral elixirs, unaware that vegetation, however spiritual, will rot when soaked in water and char when burned—how could they possibly confer longevity? Such pursuits stem from a lack of understanding. From youth, I have yearned for the Dao, and over these twenty years, I have often encountered adepts transmitting esoteric methods...

The Zhigui Ji scripture primarily elucidates the principles and lineage of alchemical practice. When the Divine Farmer (Shennong, legendary progenitor of herbal medicine) tasted hundreds of herbs, he discovered their varying properties—cold, hot, warm, or neutral—yet only cinnabar (zhusha) could simultaneously nourish both the spirit (shen) and the physical form. For those with unsettled minds, cinnabar brings tranquility; for those seeking bodily immortality, mercury must be employed. Mercury absorbs the Qi of heaven's Yang and earth's Yin, transforming into cinnabar after eight hundred years, into silver after three thousand years, and finally into gold after eighty thousand years—the longer the duration, the more indestructible its substance becomes.

Sages accelerate this natural process by mastering water and fire and harmonizing Yin-Yang, an art termed "seizing the profound mechanism of creation." From cinnabar to silver to gold, the ultimate achievement is the Golden Elixir Returned (jinye huandan), the highest-tier Daoist elixir whose consumption grants longevity. Celestial Master Xiahou (a renowned alchemist) stated: Ancient sages used supreme elixirs to nurture the spirit, middling elixirs to cultivate innate nature (xing), and lesser elixirs to heal ailments. The term "dan" (elixir) derives from its vermilion hue, while "returned elixir" (huandan) signifies the process of reverting to the origin through the cyclical movement of the Five Phases—from the "Water of Heavenly One" to the "Earth of Earthly Ten."

Naturally formed transcendent elixirs are exceedingly rare in the world. Modern cinnabar is merely the raw material for mercury and must be refined before ingestion—hence the term "alchemical refinement" (liandan). The "ninefold cyclings" (jiuzhuan) correspond to the twelve months and their associated hexagram lines (yao) from the Yijing, completing a full cycle from the first cycling (midnight, zi hour) to the ninth. These arcane methods were originally recorded in the Jinbi Longhu Jing. Though later misattributed to the Yellow Emperor, their true source traces back to the Divine Farmer.

Works like Wei Boyang’s Cantong Qi and Master Cui’s Ruyao Jing on alchemy all stem from this ancient transmission. The words of sages are as profound as celestial texts; only those who attain the Dao through oral transmission can grasp their true meaning. Zhang Pingshu (a Song-dynasty Neidan master) remarked: Though external alchemy (waidan) demands rare opportunity, its success comes readily—this is genuine cultivation. Lamenting how later seekers seldom encounter authentic teachings, the author compiles the essential doctrines of past sages into the Zhigui Ji, concluding with its core revelation: "The returned elixir requires no medicine"—true Golden Elixir practice lies not in external substances but in inner refinement.

This scripture reveals the core principles of ancient Daoist alchemy, emphasizing that true alchemy uses only lead and mercury (representing the two qi of yin and yang) as fundamental elements, while rejecting the inclusion of other mineral medicines. Here's a plain explanation:

Ancient immortals practicing alchemy focused solely on lead and mercury (symbolizing the harmonization of yin and yang) as the essential components, never using realgar, orpiment, or other "four yellows and eight stones" (referring to various mineral medicines). Mixing in other substances would instead create poison that damages the intestines and stomach. Some people process mercury with mixed herbs, mistakenly believing it can be ingested—this actually creates deadly "dead mercury" that harms people.

The text lists the toxicity of various minerals: alum can kill tigers, sal ammoniac can corrode copper, and ingesting mercury mixed with these is certainly fatal. Several Daoist masters emphasize:

1. Qingxiazi stated that all minerals turn to ash when fired, yet only cinnabar transforms into silver when placed in water

2. Immortal Ge Hong stressed that the Green Dragon and White Tiger (code names for lead and mercury) share the same essence—the elixir is achieved solely through the two qi of yin and yang

3. Laozi taught that sages create elixirs without external medicines, relying instead on the metallic structure of the "divine chamber" (the alchemical vessel)

4. Guangchengzi advocated purely refining the essence of heaven and earth's yin and yang

5. Master Yin Zhen used the metaphor: just as clams absorb moonlight to produce pearls, the spiritual elixir naturally condenses

Key points:

• True lead and mercury aren't ordinary metals but primordial vital essence (qi)
• The human body inherently contains true lead (original essence, yuanjing)
• Among the twenty-four great elixirs, "yellow sprouts" (the initial stage of elixir formation) is most crucial
• Lead represents yang within yin, mercury represents yin within yang

Finally, multiple masters criticize:

• Using the "eight stones" for alchemy will fail even after thousands of attempts
• Ordinary people don't understand the source, fruitlessly searching among minerals
• Many today betray their masters' true teachings, mistakenly treating mercury as yin medicine
• Recklessly combining gold and silver in alchemy produces opposite results

(Note: The lead and mercury mentioned are Daoist cultivation terms referring to yin-yang energies or alchemical elements within the body, not actual metals)

The Zhigui Ji scripture passage primarily discusses the essential principles of alchemical practice, which I'll render in modern vernacular:

In alchemy, one should not indiscriminately use various herbs and minerals (the "three yellows" refer to realgar, orpiment, and sulfur; the "four divines" indicate cinnabar, mercury, lead, and saltpeter). Heaven and earth operate according to their inherent patterns. Nowadays many people attempt to refine elixirs using toxic substances (dan sha refers to cinnabar), causing considerable harm. These failures stem from improper material selection, not from any inherent flaw in cinnabar itself.

Authentic alchemical practice fundamentally requires only two materials: lead and mercury (shui yin). The text cites several Daoist adepts:

• Zheng Siyuan states: The tiger represents silver (jin gong), belonging to Water and Metal phases; the dragon symbolizes mercury (cha nü), corresponding to Wood and Fire. When the Five Phases mutually generate, the Dao manifests within this process.
• Wei Boyang observes: Just as swallows cannot birth phoenixes nor foxes nurse colts, without genuine source materials, all refined products will be false.
• Guangchengzi emphasizes the crucial coordination between the Li (Fire) and Kan (Water) trigrams.
• Other adepts uniformly note: Lead and mercury must achieve yin-yang complementarity—extracting the marrow (qian chou sui) from lead and the essence (gong chou jing) from mercury—only through their union can the elixir be perfected.

Three core principles emerge:

1. Mutual control of lead and mercury: Lead (yin nature) can subdue mercury (yang nature), mirroring how stillness controls movement and grounding controls flight.

2. Purity requirement: The success of alchemy hinges on absolute purity of lead and mercury; counterfeit materials cannot produce genuine elixirs.

3. Original unity: The Supreme Venerable Sovereign (Tai Shang Lao Jun) reveals that lead and mercury originally constitute two aspects of one substance, as the ancient verse states: "One substance divides into two forms."

This passage fundamentally elucidates alchemical theory, emphasizing the use of authentic lead and mercury combined through yin-yang harmonization to refine the elixir.

This scripture primarily elucidates the symbolic meanings and interrelationships of substances like lead and mercury in alchemical practice, along with the application of the Five Phases' mutual generation and restriction principles in inner alchemy (Neidan).

Lead is called the "mother of sprouts" because metal (金) generates water (水), and water in turn generates metal—thus lead can produce "sprouts" (referring to the refined essence formed during alchemical processes). Mercury is symbolized as "wood" (木), as it transforms into flowing pearls (liquid metal) under the influence of solar Qi (气). The sun belongs to the east, which corresponds to wood in the Five Phases, hence mercury represents wood. The moon belongs to the west, associated with metal, so alchemical practice must align with these natural phenomena.

The text emphasizes that the lead and mercury used in alchemy are not ordinary substances—only their most refined essence must be selected. Lead controls mercury, and mercury subdues lead; only when the two combine can the elixir be formed. The Five Phases' cycle of generation operates as follows: wood (木) generates fire (cinnabar), fire generates earth (the true earth transformed from spiritual Qi), earth generates metal (white gold), metal generates water (black water), and water in turn generates wood (mercury). None of these are common silver, cinnabar, or ordinary earth.

Several alchemists—such as Qingxiazi, Yang Yuanyi, and Huangzi—have pointed out that ordinary people often misuse lead and mercury. Only by obtaining "true lead" (a specialized form used in alchemy) can one succeed. Beginners in Daoist practice must first grasp the essence of the Five Phases to master the infinite transformations of alchemy.

The Yin Fu Jing states that observing the Dao of heaven and following its principles is sufficient. Heaven contains the Five Phases' mutual restrictions (called the "five thieves"); only those who understand this principle will flourish. Qingxiazi explains that mercury symbolizes the Azure Dragon (青龙), corresponding to the Zhen trigram (震卦). It resides in the liver and belongs to the east (甲乙木). Wood generates fire, which governs the heart and corresponds to the south (丙丁火). These correspondences within the Five Phases form the crucial theoretical foundation of alchemy.

This scripture elucidates the principles of mutual generation and restraint among the Five Phases (Wuxing) in Daoist alchemy. The Fire of Ding (southern fire) corresponds to the Li trigram (Bagua). Originally green in color, it turns red upon encountering fire, thus transforming into cinnabar. Cinnabar symbolizes the Vermilion Bird (Zhuque, the southern divine creature), which belongs to Yang. However, when Yang reaches its extreme, it gives birth to Yin—the mercury (zhu gong) within cinnabar resembles the two solid Yang lines at the center of the Li trigram. Just as the sun harbors the Golden Crow (a three-legged raven, a Yin creature symbolizing the Dark Warrior, Xuanwu, the northern divine creature corresponding to the Kan trigram and governing the kidneys), the northern Water of Ren and Gui symbolizes lead. The Kan trigram belongs to Yin, and when Yin reaches its extreme, it gives birth to Yang—the silver within black lead resembles the broken Yin line at the center of the Kan trigram, much like the Jade Rabbit (a Yang creature) in the moon. White metal symbolizes the White Tiger (Baihu, the western divine creature), corresponding to the Dui trigram and governing the lungs. When the western Metal of Geng and Xin returns to its original nature, Water and Fire naturally harmonize, and the color shifts to yellow. Yellow governs the spleen, which belongs to the central Earth of Wu and Ji. The liver's green color corresponds to Wood as the father; the lungs' white color corresponds to Metal as the mother; the kidneys' black color corresponds to Water as the child; and the spleen's yellow color corresponds to Earth as the sovereign. The Five Phases interact through mutual generation and restraint: Metal generates Water, Water generates Wood, Wood generates Fire, Fire generates Earth, and Earth generates Metal. Conversely, Metal restrains Wood, Wood restrains Earth, Earth restrains Water, Water restrains Fire, and Fire restrains Metal. Thus, mercury (gong), belonging to Metal, can restrain Wood; cinnabar, belonging to Fire, can melt Metal; lead, belonging to Water, can extinguish Fire; and when Water is excessive, Earth is used to suppress it. By applying these principles of mutual generation and restraint, the Great Elixir (Golden Elixir, Jindan) can be refined.

The text then cites several Daoist masters: The Jinbi Jing states that the Five Phases are the key to alchemy—the Kan trigram contains the essence of Metal, while the Li trigram contains the light of Fire. Metal and Fire restrain each other, while Water and Earth control one another. When Earth flourishes, Metal perishes; balance is essential for success. Chunyu Shutong explains that Wood is injured by Metal, Water is restrained by Earth, Earth is broken by Wood, and Metal is melted by Fire—these are the natural laws of the Five Phases' mutual restraint. Master Cao emphasizes pairing the Azure Dragon (Qinglong, Wood) of the east with the White Tiger (Metal) of the west and uniting the Vermilion Bird (Fire) of the south with the Dark Warrior (Water) of the north, with the central Earth serving as the crucial harmonizing element. Yan Junping correlates the numbers one through five with Metal, Wood, Water, Fire, and Earth, asserting that understanding this principle leads to longevity. Zhang Pingshu declares that when the two substances of Yin and Yang (Dragon and Tiger) unite and the Five Phases are complete, the Golden Elixir can be perfected. He underscores the pivotal role of Earth in alchemy—without it, the Five Phases cannot mutually generate, and the Golden Elixir cannot form.

This scripture primarily discusses the "fire timing" (referring to the control of heat intensity and temporal precision in alchemical processes) and the principles of Yin-Yang transformation during Neidan (internal alchemy) practice. The core teachings can be understood as follows:

The master Qingxiazi states that the period from the first lunar month to the seventh month's Shen hour (3-5 PM) is called the "Seven Returns," while the cycle from the eleventh month to the seventh month is termed the "Nine Reversions." The initial kindling of the alchemical fire corresponds to the state of nascent Yang energy. The commentary explains that unless lead and mercury (fundamental alchemical ingredients) undergo this sevenfold and ninefold refinement process, any forcibly produced elixir will lack spiritual efficacy.

Specifically:

• The alchemical cycle follows the hexagram sequence: Fu (Return) in the 11th month, Lin (Approach) in the 12th, Tai (Peace) in the 1st, Dazhuang (Great Strength) in the 2nd, Guai (Resolution) in the 3rd, Qian (Heaven) in the 4th, Gou (Encounter) in the 5th, Dun (Retreat) in the 6th, Pi (Standstill) in the 7th, Guan (Contemplation) in the 8th, Bo (Splitting Apart) in the 9th, and Kun (Earth) in the 10th month—corresponding to the 24 solar terms.
• A successfully refined Golden Elixir manifests as purple-red, indicating abundant Yin-Yang energies, dense material quality, and substantial weight—the true elixir capable of infinite transformations.

The text further elucidates Yin-Yang dynamics:

• The spring months (Zhi, Chou, Yin) and summer months (Mao, Chen, Si) represent six months of pure Yang dominance, where Yin energy seeks Yang's assistance, gradually manifesting water's qualities.
• The autumn months (Wu, Wei, Shen) and winter months (You, Xu, Hai) represent six months of pure Yin dominance, where Yang energy seeks Yin's support, causing water vapor to condense into metal, which then disperses back into water.

Fire and water energies mutually temper each other while their forms intermingle in constant transformation. Water ascends through fire's influence, while metal descends through fire's action—their harmonious interaction within the alchemical cauldron ultimately produces the mysteriously potent Golden Elixir.

The Golden Luminary Scripture (Jinbi Jing) and Kinship of the Three (Cantong Qi) further clarify:

• The alchemical cycle follows lunar phases, beginning with the Kun hexagram and progressing through Zhen, Dui, Qian, Xun, and Gen—mirroring the moon's waxing, fullness, and waning.
• A complete refinement cycle spans 600 watches (60 days), incorporating the rhythms of day/night and the four seasons. Time accumulates into days, days into months, and months into years.
• The twelve daily watches divide equally into Yin and Yang phases, with the four most Yang-intensive periods requiring specific fire regulation. The Ancient Fire Dragon Scripture describes the "Luminous Dragon" embodying pure Yang Qi, appearing azure—a symbol of generative potential.

Through hexagram transitions, lunar phases, and seasonal changes, this scripture demonstrates that alchemical practice must strictly follow cosmic Yin-Yang rhythms with precise fire timing control.

The Zhigui Ji (Guidance Compendium) scripture primarily elucidates the mysteries of alchemical fire tempering and the essential principles of Dao transmission:

Regarding alchemical fire tempering:

The fire chamber (referring to the alchemical furnace) must absorb 4,330 years of heaven-earth primordial Qi (vital energy) to form the "fire dragon." According to the Jinjing Taisu Jing (Golden Essence and Great Simplicity Scripture), cinnabar (the primary alchemical ingredient) contains pure Yang Qi and ultimate Yin Jing (essence), requiring 4,320 years of Yin-Yang transformation to complete the perfected elixir. Master Ge (the Daoist immortal) stated that the specific methods of bathing fire tempering (the crucial alchemical process) cannot be recorded in writing—they must be orally transmitted mind-to-mind upon encountering a genuine Dao-realized person. While past sages meticulously documented alchemical methods, their subtle profundities defy verbal expression, becoming comprehensible only to true cultivators through practical experience.

Concerning Dao transmission:

The principles of celestial movement and Yin-Yang transformation were thoroughly recorded in classical texts by ancient sages. Yet ignorant individuals cling stubbornly to personal views, distrusting sage teachings while paradoxically claiming celestial secrets cannot be revealed—thus straying from the Dao. This reflects not the sages' unwillingness to teach, but these individuals' disharmony with Dao principles and inner incomprehension. The Yinfu Jing (Hidden Talisman Scripture)'s warning that "revealing celestial secrets brings three kalpas of downfall" refers to those who misuse the Great Dao and violate heavenly principles—not that the Dao cannot be transmitted.

Just as the ways of Yao-Shun and Confucius were preserved in the Six Classics, or Buddhist scriptures spread universally, petty minds gain no understanding from reading them, nor do wicked persons grasp essentials through recitation. The texts of Fuxi and Shennong have circulated since antiquity—what secrecy remains? The crux lies in aligning one's heart with the Dao and harmonizing conduct with celestial principles. The author recounts examining over a hundred alchemical scriptures, discovering divergent expressions conveying unified principles, and thus compiling this text from the most accessible materials.

Concluding verses reveal: The Great Dao's transmission originated with the Jia Clan (possibly referring to the Yellow Emperor or Daoism's primordial patriarch). This passage emphasizes cultivation through practical realization, opposing mystical obfuscation while affirming that true celestial secrets manifest in heavenly principle-aligned conduct.

This passage addresses controversies surrounding Daoist alchemical practices and methods for discerning authenticity.

When discussing alchemy (neidan/waidan) today, various schools often present contradictory claims. Take for example the term "Divine Water and Blossoming Pool" (shenshui huachi), an important alchemical substance and apparatus. Originally appearing in Li Quan's commentary on the Yinfu Jing (Scripture of the Hidden Accord), later generations mistakenly cited it as part of the canonical text itself. Such cases arise when people rely solely on hearsay without thorough investigation of sources.

The author observes that these records were initially meant to convey principles metaphorically, yet later practitioners mistook the symbols for literal truths ("forgetting the fish-trap while clutching the fish" — an allusion to Zhuangzi's warning against fixating on tools while losing sight of their purpose). Many implausible elements in these texts were actually fabrications by fangshi (esoteric practitioners) dating back to the Qin and Han dynasties.

The passage concludes with a method for discernment: scholars should employ rational judgment to naturally distinguish authenticity. The message is clear — rather than blindly accepting alchemical accounts, one must apply critical thinking to evaluate them.

(Note: "Shenshui huachi" rendered descriptively as no standard translation exists; "fangshi" kept in pinyin as a technical term for pre-Daoist occult specialists)
