《亶甲集》

Interpretation of the "Danji Collection"

By Zhao Min, the Zhenren (Perfected Person) of Western Qin

Those who seek the path to immortality must thoroughly investigate the origin of the great Dao (the Way). When you understand that the Crimson Dragon (heart fire) resides in the Black Sea (kidney water), you must let the White Tiger (lung metal) rest in the Vermilion Palace (heart). When the energies of the Five Phases (Wood, Fire, Earth, Metal, Water) gather in the Golden Region (Dantian, energy center), and after nine cycles of refinement, they return to the Purple Mansion (upper Dantian). If you can perceive this wondrous celestial mystery, you should guide your descendants to cultivate early.

Through long and diligent practice, aspiring to the state of Xiyi (tranquil non-action), one may finally encounter a Zhenren (Perfected Person) who reveals the gateway to cultivation. Understanding how Kan (Water) and Li (Fire) harmonize like nesting in a jade tree, allowing the essence (Jing) and Qi (vital energy) within the body to circulate like a celestial chariot (microcosmic orbit). When the Dragon (heart) and Tiger (kidneys) unite to stabilize the chamber of Shen (spirit), and the sun and moon cycle to form a precious flower—after the seven returns and nine restorations (complete alchemical cycles)—consuming a single Golden Elixir (Jindan) will lead to transcendence.

Living in seclusion, studying among the mundane, wandering the world while preserving innate purity—sincere cultivation eventually grants extraordinary opportunity. Realizing that nurturing the Dao is the true reason for dwelling in the world, the primal Qi (vital energy) gathers in the Dantian like phoenix marrow (refined essence), while the immortal embryo is nurtured between the two crescents (phases of the moon). When Yin and Yang energies are fully refined into the Golden Elixir, one becomes an immortal dwelling in the cavern-heavens.

With a solitary temperament and extraordinary skill, one may traverse the world yet rarely meet a kindred spirit. If you can make the Sun’s soul (Yang spirit) dwell with the Moon’s essence (Yin Jing), and comprehend the transformations of Yin and Yang—regulating the mundane fire in the cauldron (body) and firmly guarding the sacred embryo (Golden Elixir) within the furnace—after eighty-one days of flawless fire management, consuming the Elixir will transform you like a dog becoming a dragon.

Shedding the mortal body is no impossible feat; the principle of Metal (Jin) and Wood (Mu) generating each other is profound. Gathering the Golden Crow (solar essence) into the Northern Sea (kidneys), accompanying the Jade Rabbit (lunar essence) through the autumn (lungs)—when the three powers (Heaven, Earth, and Man) unite with the aid of Li Fire, a hundred days of refinement will complete the medicine’s potency. Persisting in its consumption naturally extends life; even as seas turn to mulberry fields, your countenance will never fade.

True achievement lies in Wuwei (non-action), transcending deliberate effort to merge with the sacred work. Understanding the positions of Kan (Water) and Li (Fire), allowing the Crow (sun) and Rabbit (moon) to move east and west—the Elixir transforms rubble into treasure, and the aged who partake return to youth. Few grasp this profound Dao, yet its truth is hidden between the lines.

After attaining the Dao, leaving Qin behind, singing wildly as a carefree wanderer—employing the creative power of Yin-Yang, gathering lead (essential energy) and mercury (spiritual essence) to nourish yourself. Do not resent these repeated admonitions, for the moment of cultivation may slip away in an instant. If you can partake of the immortal’s Elixir, serving in court and achieving merit will not hinder you.

To seek the realm of eternal life, the pairing of Jia (Wood) and Geng (Metal) is the king of medicines. It expels Yin evils like a cicada shedding its shell and further nourishes the Yang spirit to prolong life. Unafraid of seas drying or mountains crumbling, eternal youth aligns you with the Dao’s truth.

Plain Interpretation of the "Danjia Collection":

The human body inevitably ages with graying hair, but those who devote themselves to cultivation and early comprehension of the Dao's true meaning can avert calamities. Only those who truly understand the state of "emptiness and non-being" can fathom those profound and unfathomable mysteries. Like an armored dragon (symbolizing yang vigor) and a tiger crouching in Geng Metal (symbolizing yin essence), the transformations of Yin-Yang conceal profound secrets. The Eight Trigrams (Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui) divide into the Four Symbols (Great Yang, Lesser Yang, Great Yin, Lesser Yin), while the Nine Heavens correspond to the three Dantian in the human body (the upper Dantian or Muddy Pellet Palace, middle Dantian or Scarlet Palace, and lower Dantian or Sea of Qi). The key to transcending from the mundane to immortality lies in gathering the Primordial True One Qi (referred to metaphorically as "jadeite treasure").

Even reading ten thousand volumes of Daoist scriptures is futile without authentic oral transmission. The dragon (yang) flying from the Li Palace (southern fire position) and the tiger (yin) moving through the Kan Palace (northern water position) embody the principle of Yin-Yang interaction that few can comprehend. Practitioners must grasp the mystery of "generating being from non-being" to avoid wasting their lives.

A single grain of cinnabar (symbolizing the internal elixir) can rejuvenate an aging body, containing the secrets of cosmic creation. Ingesting it revitalizes the organs, causing yin energies to recede and return to their origin—startling ordinary people—while yang energies flourish and return to purity, astonishing sages. The ancient immortals attained their status precisely by taking this medicine (the internal elixir), as there exists no other path to immortality.

Most overlook the "gold within water" (true yang within the kidneys), yet the deepest teachings of alchemical texts reside here. Only by understanding the interplay of Kan (water) and Li (fire) can one master the celestial cycles of Mao (east) and You (west). To return the spirit to the Purple Mansion (upper Dantian), one must begin with Bing Fire (heart fire); to gather the Primordial Essence (symbolized as "jade flowers"), one must seek it within Ren Water (kidney water). These verses directly point to essential cultivation methods—do not distract yourself with other pursuits.

Few understand the phenomena within the "gourd" (Dantian). Those who comprehend will not go astray, and those who fully penetrate these truths are exceedingly rare. Do not rely solely on textual interpretations—authentic oral transmission is essential to avoid deviation. Extending life requires the power of the Mysterious Pearl (internal elixir), while refining the medicine demands deep study of creation's mysteries. Ingesting the spiritual elixir dispels yin pathogens, enabling the pure yang body to ascend to the Great Void.

Ancestral virtue may lead descendants to immortality, but the efficacy of the Returned Elixir (internal elixir) must still be verified. The mutual generation of metal and water returns to the Central Palace (earth of Wu and Ji), circulating through the celestial cycles of Yin and Shen hours. When the furnace opens, five-colored radiance illuminates the Dantian; when the elixir enters the abdomen, the Three Hun souls (Tai Guang, Shuang Ling, You Jing) return to the celestial grottoes. The hidden meanings in these verses require heartfelt contemplation—no need to seek alternative explanations.

Gathering yin (collecting kidney essence) and receiving yang (drawing heart fire) must align with trigram and line principles. The dragon (heart) and tiger (kidneys) couple within the crucible (Dantian). When dragon meets tiger, maintain the vigilance of a jackal; when tiger encounters dragon, be as alert as a sparrow-hawk. Seven refinements through fire phases can lead to sagehood, while a single bathing (gentle nurturing) awakens the spiritual embryo. The elixir transforms mortal substance, much like a phoenix arising from a chicken fed with cinnabar.

Refining the immortal elixir holds further mysteries—an unbroken lineage of true methods from ancient times to the present. Fully comprehending Ren...

Plain Interpretation of the "Dan Jia Collection":

To harness the Golden Tiger (referring to fire control in Neidan/internal alchemy practice) and the Azure Lad (symbolizing the primordial spirit) to seek the Fire Ox (representing the body's yang energy), these cultivation techniques require continuous day-and-night cycles. The movement of the sun and moon resembles the alternation of spring and autumn—only then does one realize how difficult it is to enter this path of practice. Sadly, most seekers in this world stray from the true way.

Without authentic transmission, the principles remain elusive, wasting one's vital energy in vain. One must guide the Crimson Infant (the heart-mind) to depart from the Mystic Chamber (the brain) while ensuring the Yellow Matron (the spleen-intention) guards the Purple Blossom (kidney essence). The slightest deviation in Qi (vital energy) can scatter the Shen (spirit); though the Six Lines (celestial cycles) may be complete, the elixir remains hard to refine. I urge you to diligently practice ingestion—when Jing (essence), Qi, and Shen are abundant, the body will naturally grow light and vigorous.

Few understand the mysteries between the Li Palace (heart) and the Kan Position (kidney), and even those who know may not grasp the root. The Gui Mother (kidney yin) often accompanies the White Dragon (lung Qi), while the Ding Elder (heart fire) must nourish the Black Tortoise (kidney essence). Within a thousand days, one may pay homage at the Yellow Court (middle Dantian), resting by the Twelve-Storied Tower (trachea) beneath the Purple Canopy (saliva). Do not be surprised by the directness of these teachings—with years of practice, understanding will come naturally.

Carry your lute and wine to walk with the Dao, and ponder how much time a human life truly holds? Be joyful when it's time for joy; relax where relaxation is due. If you see the Infant (true yang in the kidneys) in the water, you should hear the Charming Maiden (true yin in the heart) singing in the fire. Harmonize them rightly, and longevity will follow—let the days and months fly by like a shuttle.

In the depths of the Northern Sea lies the Bream Fish (kidney essence); hook it to pair with the Moon Toad (yin essence) for refining medicine. Guide it into the Yellow Court to pay respects at the Sacred Palace, then plant it in the Purple Mansion (upper Dantian) to grow into an immortal elixir. Bones harden like jade, the face unchanged; intestines transform into sinews, reversing age. Yin energy naturally dissolves its name, while the Yang Spirit (pure primordial spirit) no longer leaks through the Three Carriages (loss of essence, Qi, or Shen).

Pluck the Jade Stamen (saliva) from the Celestial Pool (under the tongue)—its coolness brings joy to the Departing Maiden (heart-mind). Hand in hand, enter the tent of the Spring Lord (liver wood), then ascend the altar of the Red Emperor (heart fire) in turn. Within a hundred marks (a day), cycle through the Jiazi (celestial orbits); after ten thousand days of practice, the Divine Elixir is complete. Mortals who encounter this become transcendent guests; sparrows who partake transform into phoenixes.

Cultivate De (virtue) daily to meet a true master—their words reveal the unity of emptiness. Once you grasp the immortals' secrets of lead and mercury (yin and yang), worldly fame and wealth will seem hollow. No pile of gold or jade can compare; descendants' blessings instead become burdens. Why rush to worship stars and the moon? When the Dao is achieved, past karmic connections will shine through.

The lost fail to recognize the Gold in Water (true yang in the kidneys), vainly searching to the ends of the earth. Understand that Black Lead (kidney essence) becomes a supreme treasure, and Crimson Mercury (heart-mind) naturally cools into a serene grove. The Azure Lad (primordial spirit) sings palace melodies well; the Kan Mother (kidney Qi) plays zither notes in perfect tune. Step into the Gourd (Dantian) to feast together—day and night, revel like dragons chanting in joy.

This Danji Collection primarily elucidates the principles and methods of Daoist Neidan (internal alchemy) cultivation.

The opening passage reveals that the Yinfu Jing and Daode Jing disclose celestial secrets. Practitioners should cherish their innate purity (primordial Qi) with maternal devotion, guarding against contamination by acquired distractions. The principle that "fire (heart fire) arises from wood (liver)" and "water (kidney Jing) enters Li (heart)" forms the foundation of cultivation. Though worldly methods abound, none surpass the elixir's power to eradicate the "Three Corpses" (Daoist term for three malevolent spirits residing in the human body).

The second section expounds the profound mystery of the Dao, emphasizing alignment with nature's flow. While all things emerge from Kan (water), their root lies in Qian (heaven). Neidan practice stabilizes the Shen (spirit), while consuming immortal herbs (purple stamens) lightens the physical form. Mastery grants longevity surpassing eight millennia, rendering earthly immortality unnecessary.

The third passage describes how perfected beings gather jade blossoms (refined Jing-Qi), uniting mercury (Shen) with lead (primordial Qi). When the Four Symbols (Wood, Fire, Metal, Water) return to central Earth, and the Five Directions (east, south, west, north, center) unite, the "Purple River Chariot" (Neidan term for perfected elixir) manifests. This transforms aged frames into vigorous vessels, echoing how even the poultry and dogs of Prince Huainan ascended upon his attainment of the Dao.

The fourth segment declares that perfected elixirs enable one to move undetected through worldly realms, whereas hermits lacking authentic transmission gain nothing. Universal principles interconnect—the Three Dantians must flow unimpeded. Successful practitioners maintain infantile complexions, their hair untouched by white.

The fifth portion details golden elixir effects: unobstructed Qi-blood circulation, marrow cleansing, and rejuvenation. By harvesting the "Scarlet Maiden" (Shen) from Yang Qi and pairing it with the "White-Haired Elder" (primordial Qi) from Yin Qi, deathless longevity is achieved.

The sixth passage asserts the Dao's supremacy between heaven and earth, noting those scant in virtue cannot fathom lead-mercury mysteries. Skeptics dismiss lead extraction (gathering primordial Qi) as immaterial, focusing solely on mercury refinement (cultivating Shen) to nourish the Dantian. Yet the Yellow Emperor ascended precisely through ninefold-refined golden elixirs.

The finale laments humanity's futile pursuits: though aware all returns to dust, they cling to treasures. A single method contains myriad principles; mere elixir grains extend life by centuries. The verses urge awakening—placing no hope in hypothetical afterlives.
