《大還丹金虎白龍論》

Discourse on the Golden Tiger and White Dragon of the Great Returned Elixir: A Modern Interpretation

This is an alchemical treatise composed by the recluse Huanyangzi of Sumen Mountain. The text primarily reveals the essential techniques for refining the Golden Elixir (Jindan), the highest attainment in Daoist cultivation:

The key to elixir refinement lies in harmonizing Yin and Yang—the Golden Tiger represents lead, while the White Dragon symbolizes mercury. Through cultivation, one can prolong life and preserve the physical form, which requires nurturing the spirit (Shen) and vital energy (Qi), as well as refining the earthly soul (Po) into the celestial soul (Hun). The specific method involves:

• Transforming the Yin nature of the "Dragon" (mercury) into Yang
• Transforming the Yang nature of the "Tiger" (lead) into Yin
• Merging spirit and energy, refining Po into Hun
• When the breath becomes tranquil and the spirit harmonized, the souls unite, leading to the sacred state

True Golden Elixir cultivation entails:

1. The fusion of Dragon and Tiger (lead and mercury) to form elixir liquid

2. The convergence of spirit and energy to manifest the true divine

3. The saliva in the mouth serving as the "Jade Pool" (the crucible of alchemy)

4. The state of "Embracing the One" (Baoyi)—unity with the Dao—achieved by letting go of distracting thoughts

To ascend as an immortal, one must ingest the elixir of the true soul; to attain longevity, one must nourish the essence (Jing), soul, and spiritual energy. This is the secret of the Golden Elixir and the essential method for achieving immortality. Successful cultivation enables one to:

• Transform both spirit and physical constitution
• Manifest or withdraw the body at will
• Reveal the true spirit freely
• Traverse time and space
• Ascend to the Purple Mansion and Jade Purity (the highest celestial realm)
• Roam the azure heavens and golden palaces (the immortal realms)

The text critiques erroneous alchemical practices:

• Mistaking ordinary metals for Dragon and Tiger
• Disrupting the balance of Yin and Yang
• Inverting the principles of water and fire
• Exaggerating the efficacy of certain minerals
• Disregarding classical teachings to establish arbitrary rules
• Attempting self-study without proper guidance

These mistakes lead to failed cultivation, wasting effort and spirit in vain.

The author claims to have long secluded himself in mountain forests, devoting himself to:

• Cultivating spirit and energy
• Returning to the primordial origin
• Comprehending the principles of lead and mercury
• Studying alchemical scriptures and Daoist texts

Ultimately, he attained the correct method of elixir refinement:

1. Properly employing Dragon and Tiger (lead and mercury)

2. Harmonizing Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water)

3. Aligning the positions of Kan (water) and Li (fire)

4. Refining the essence of the sun and moon

5. Producing the Five-Colored Mysterious Frost (the Golden Elixir)

6. Manifesting the radiant glow of pure snow (signs of the elixir’s completion)

The author emphasizes that these sacred formulas and principles are genuine and unfailing, and having fully grasped their profundity, he composed this preface in two parts to elucidate them.

"Discourse on the Great Reverted Elixir's Golden Tiger and White Dragon" – Modern Interpretation

[Understanding the Yellow Sprout]

The Yellow Sprout is the product of Heaven and Earth's Yin-Yang interaction. Within Yang Qi lies a Yin essence (Yin soul), while within Yin Qi resides Yang energy (Yang spirit). When Yang manifests its radiance, it shines brilliantly; when Yin achieves purity, it becomes translucent like fine jade. It outshines the moon's glow and rivals the sun's radiance in painting crimson clouds. Its form resembles overlapping scales, growing in Yang positions yet secretly harmonizing with Yin. It governs the Five Metals (gold, silver, copper, iron, tin) and Eight Minerals (cinnabar, orpiment, etc.)—those who comprehend its principles may ascend to the heavens, while the ignorant remain unaccomplished throughout life. Though people encounter it daily, they fail to recognize it, growing old with white hair yet achieving nothing.

Poetic explanation: The Yellow Sprout forms through Heaven-Earth communion, originating from the Water position (North). The sun and moon's cycles perfect its soul and spirit; Yin-Yang union gives birth to the Dragon and Tiger (lead and mercury). Though ubiquitous in the human world, none know its true name.

[Understanding Lead and Mercury]

To refine the Golden Elixir (Jindan), one must first comprehend lead and mercury's true nature. Lead contains Yin marrow (Tiger, Kan trigram position), while mercury generates Yang essence (Dragon, Li trigram position). The Kan moon and Li sun serve as communicative mediums; the Li maiden and Kan youth form a cyclical system. Lead's metallic nature resembles coarse cloth concealing jade; mercury's wooden quality is like red garments hiding timber. True lead isn't common tin, nor is true mercury ordinary silver—lead forms Heaven-Earth's foundation, while mercury embodies Yin-Yang's numinous energy.

Lead harbors the sun's Yang soul; mercury contains the moon's Yin spirit. By extracting the Five Phases' essences, they coalesce into golden fluid; by combining Yin-Yang's quintessential manifestations. The waxing and waning of sun and moon cause souls and spirits to ebb and flow; only through Yin-Yang interaction can the Dragon-Tiger Elixir be forged. When Yang restrains Yin, the Golden Elixir's embryo forms; when Yin transforms into Yang, the Divine Elixir's substance is achieved. Perfect Yin-Yang balance yields an immortal elixir transcending worldly existence; through water-fire refinement emerges cloud-riding celestial liquor, ultimately manifesting as crimson-hued elixir blossoms upon the alchemical cauldron.

(Note: "Dragon-Tiger" denotes lead and mercury's Yin-Yang attributes; "Kan-Li" refers to the water and fire trigrams in the Bagua, representing core alchemical concepts.)

This scripture reveals the esoteric art of Daoist alchemy for attaining immortality, using poetic language to depict the elixir refinement process and spiritual cultivation states.

The alchemical process is vividly portrayed: the furnace emits radiant light like auspicious snow, as resplendent as morning clouds, resembling the first rays of dawn; it also appears as clear as the autumn moon reflected in a cold pond. When grinding medicinal ingredients, they release fragrant aromas, while crushed materials shimmer with translucent brilliance. After meticulous refinement, the elixir becomes a precious treasure - consuming just one pellet enables ascension to celestial realms and transformation into an immortal.

The author laments how ordinary people chase fame and wealth, their hundred-year lifespan passing like a fleeting dream. To halt time's passage and transcend worldly existence, one must comprehend the secret of refining the elixir of immortality. This divine medicine requires gathering the essential essences of heaven and earth's Yin-Yang (referring to nature's two fundamental energies), harmonizing the "dragon and tiger" (representing internal Yin and Yang Qi), and fusing the Red Emperor's essence from the Li Palace (heart) with the White Dragon's fluids from the Kan Gate (kidneys).

Elixir refinement demands strict adherence to firing cycles, requiring the "nine revolutions" (nine refinement stages) and a thousand days to complete. When five-colored auroras rise from the furnace and the cauldron's liquid turns crimson, ingesting a single pellet enables ascension to the Three Pure Realms (Daoism's highest celestial abode), riding cranes or dragons beyond the cycle of life and death.

The scripture further explains that alchemy must follow Yin-Yang and Five Phases principles: combining solar essence (sun's energy) with lunar soul (moon's energy), merging Metal (lungs) and Wood (liver), and harmonizing Yin-Yang (the two fundamental energies) in proper sequence. After ten months of "gestation" (the elixir's incubation process), the immortal path is ultimately achieved.

The concluding passages contain master-disciple exchanges: the master encourages the disciple to find tranquility amidst busyness and cherish time; observes worldly impermanence through Zhuangzi's butterfly dream; and prophesies the disciple's eventual enrollment in celestial registers to feast with immortals in golden halls. The master transmits the true alchemical formulas before hosting a farewell banquet.

This scripture integrates both Waidan (external alchemy) and Neidan (internal cultivation) practices, using magnificent imagery to manifest Daoism's ideal realm of pursuing longevity and transcending mundane existence.

This text is an essay on alchemical cultivation written in the winter of 886 CE (the second year of Emperor Xizong's Guangqi reign during the Tang dynasty) by Daoist priest Du Xidun (courtesy name Wangji, Daoist name Yongyangzi). Living in turbulent times, Du had retreated to the banks of the Wen River to avoid political turmoil.

The passage describes his close friendship with a Daoist recluse called "Lord of Nanyang." Their bond transcended worldly fame and profit—whenever they met, they would spend entire days discussing cultivation, delving into mysteries "profound beyond profundity." Du presented Lord of Nanyang with alchemical secrets transmitted by his own master, emphatically instructing him to treasure them and never casually reveal them to ordinary people.

The text stresses that the path of cultivation and alchemy belongs to realms beyond conventional society and must not be made known to common folk. Divulging celestial secrets would not only bring divine punishment upon the offender but also implicate nine generations of ancestors. Concluding with an oath sworn upon "green mountains and white clouds," Du repeatedly urges Lord of Nanyang to guard these teachings with utmost secrecy.

Terms like the "Great Return Elixir (Dahuandan)," "Golden Tiger (Jinhu)," and "White Dragon (Bailong)" are specialized Daoist alchemical terminology referring to distinct elixirs and essential components. The entire essay embodies the Daoist tradition of "secret transmission," emphasizing that matters of cultivation must be treated with solemn reverence.
