《諸真論還丹訣》

Interpretation of "The Various Authentic Discourses on the Reverted Elixir Formula"

[Ten Odes of the Jade Pot]

1. In alchemical practice, the liver Qi (Azure Dragon) must harmonize with lung Qi (White Tiger), while heart fire (Vermilion Bird) needs to merge with kidney water (Black Tortoise). To grasp the foundation of alchemy, one must take the central spleen earth (Wu-Ji earth) as the root.

2. The Azure Dragon originally stems from cinnabar (symbolizing heart fire), while the White Tiger returns to black metal (symbolizing kidney water). Ancient immortals called it the "essence of the divine dragon," while the Huainanzi refers to it as "autumn stone" (representing the elixir).

3. The divine water (referring to mercury, symbolizing the original spirit) is fundamentally the essence of mercury, and the eastern Wood virtue (liver Qi) initiates the birth of Yang energy. The southern heart fire is the dominant force—only by comprehending this principle can the practitioner align with the true Dao.

4. When the dragon and tiger energies meet in the Dantian (womb), the two essences blend like blossoming flowers. Focus on observing the signs of the nascent Yang (the birth of Yang at the winter solstice), and only after nine cycles of refinement can the elixir be naturally perfected.

5. At the hour of Jia-Wu (noon), when Yang culminates and Yin is born, the six hexagrams have already transitioned into the Qian palace (pure Yang). The wondrous methods of the immortals have been passed down since ancient times, yet ordinary people remain lost in their pursuit of the Dao.

[Key Points of Alchemy]

• Cinnabar originates from metal (lungs), and mercury is concealed within lead (kidneys). These mysteries are not lightly transmitted. It is not that the method of reverting the elixir is withheld—it is only the fear of leaking celestial secrets and incurring divine retribution.

• The Yin and Yang energies circulate ceaselessly, interacting with profound subtlety. They not only transform matter but also dispel calamities and malevolent influences.

[Warnings for Cultivation]

Throughout history, practitioners of the Dao have often evoked sighs—time flies, and youth fades. Many lose their way, unaware of what true "yellow sprouts" (the nascent appearance of the elixir) even are.

[Signs of Elixir Formation]

When the tenth month brings frost and snow, the yellow sprouts within the body mature and radiate luster. When the practitioner witnesses the ripening of these sprouts, they naturally subdue the golden tiger (lung Qi) and the azure dragon (liver Qi).

[Effects of Ingesting the Elixir]

Consuming even a speck-sized pure elixir can condense the true Qi and calm the spirit. Not only can it transform matter to aid the impoverished, but it also bestows the body with immortality.

[Qingxiazi's Praise for the Golden-Blue Dragon-Tiger Classic]

Though the dragon and tiger have names, they lack form. The tiger hides in the dragon palace (lung Qi concealed within the kidneys), and when the dragon moves, the tiger follows (liver and lung Qi moving in tandem). They share a single origin, much like human nature remains inseparable from the self.

[Essential Formula of the True Cauldron]

Alchemy first requires refining the "true cauldron" (Dantian). When the effort reaches fruition, marvels manifest naturally. Mundane substances cannot bear the elixir—only when Yin and Yang harmonize like the undifferentiated primal Qi can it succeed.

[In Praise of Wei Boyang's Zhouyi Cantongqi]

Wei Boyang's three-volume Zhouyi Cantongqi elucidates in detail the true meaning of the reverted elixir. Refining this elixir is not difficult—its form resembles the blending of yolk and egg white within an egg.

This scripture elucidates the core principles of Daoist Neidan (internal alchemy) cultivation through metaphorical language:

The cultivation principle reveals that "within the smallest matter lies the same cosmic pattern as heaven and earth" - demonstrating how the human microcosm operates according to the same laws as the macrocosm. Practitioners must balance the water (Yin Qi) and fire (Yang Qi), understanding that true water (kidney Jing/essence) and true Yang (heart fire) share the same origin. This profound mystery mirrors how the sun (Yang) and moon (Yin) mutually depend on each other, requiring the harmonious interaction of the Kan (water) and Li (fire) trigrams from the Bagua (Eight Trigrams).

Fire regulation follows natural cycles - Yang Qi ascends like spring and summer, while Yin Qi descends like autumn and winter. The practitioner must precisely time their practice like simmering medicine in a cauldron, strictly adhering to these natural rhythms without violating temporal patterns.

The scripture proclaims "every household possesses the medicine of longevity" - indicating that the true elixir (Jing, Qi, and Shen) exists within all people, though most fail to utilize it properly. The authentic Golden Elixir (Jindan) isn't sought externally but cultivated internally.

The Rongcheng Gong's Neidan verses describe:

• "Primordial azure" refers to preheaven Yuan Qi (original energy), with the sun and moon symbolizing the lower Dantian (Yin) and middle Dantian (Yang) energies.
• When primordial energy, saliva, and breath combine in the "jade pool" (mouth) and return to the "golden chamber" (Dantian), they form an "mysterious pearl" (Xuanzhu) - a golden elixir the size of a tangerine with honey-like sweetness.
• After obtaining this elixir, practitioners must guard it meticulously, avoiding leakage particularly through sexual activity.
• After nine years of sustained practice, vital essences condense into the "internal returned elixir," with bodily fluids nourishing the entire system (the nine-cycle eight-jewel elixir).
• Ultimately achieving cosmic longevity, the refined essences transform into jade and gold (symbolizing purified energy), with the mysterious pearl residing in the lungs (golden chamber) and the sea of Qi anchored in the heart.

Note: Neidan practice constitutes a vital Daoist longevity technique that refines Jing (essence), Qi (energy), and Shen (spirit) through breath regulation and visualization. Terms like "mysterious pearl" and "nine-cycle elixir" represent different stages of internal alchemical transformation.

This passage from "Cao Shengtu's Song of Lead and Mercury" expounds core concepts of Daoist alchemy. The poem uses metaphorical language to explain the principles of elixir refinement:

Though gold is precious, the true secret of alchemy lies in mastering the cyclical movement of north and south (symbolizing Yin-Yang). Few truly understand this principle—those who do often dwell in reclusion like the immortals of Penglai. Ordinary people wouldn't recognize an alchemical master even if they met one, just as they cannot truly comprehend the sun, moon and stars.

The poem emphasizes that the essence of alchemy is transforming the "One Qi" (primordial energy) into "Golden Liquid" (the elixir). This requires following the generative and controlling cycles of the Five Phases (Wood, Fire, Earth, Metal, Water). Though the power of the Five Phases permeates all things, only genuine practitioners can discern its subtle workings.

Lead and mercury (alchemical symbols for Yin-Yang) are the primary materials. Water represents Yin while stone embodies Yang, with the "Central Palace" (Dantian) serving as the alchemical crucible. The interaction of water and fire mirrors the union of Yin-Yang, like the harmonious pairing of husband and wife. After a hundred refinements (symbolizing complete fire phases) in the Palace of Li (heart-fire position), cinnabar (the Golden Elixir) will crystallize.

The true Golden Elixir resembles a pearl—originally colorless, it manifests watery nature when meeting water and transforms into golden liquid when encountering fire. Sages call it the "Divine Medicine," while realized beings name it the "Precious Art." Yet worldly scholars only discuss minerals as lifeless substances, unaware how to transmute them into living elixir.

The poem makes a crucial distinction: To remove the dark impurities from lead, one must supplement primordial energy with primordial energy—ordinary sand and stone won't suffice. Rare materials like realgar and cinnabar needn't be obsessively pursued; even mercury isn't ultimately special. Just as bamboo repairs bamboo and wood mends wood, the human body requires primordial Qi for nourishment. All external substances are but aids—the true secret lies in comprehending the mutual nourishment of water and fire, the key to attaining immortality.

Though lead and mercury have many alternate names, their fundamental principles reside within the Five Phases. Those who cultivate according to this method and ingest the perfected elixir shall achieve longevity.
