《太上洞房內經註》

This scripture primarily expounds the essential principles and taboos of cultivating the Dao to attain immortality. Let me explain:

While the pursuit of immortality through Daoist cultivation is possible, achieving it is profoundly difficult. The key lies in several aspects: maintaining pure intention, refining subtle Qi (vital energy), and attaining deep meditative states. The scripture cites various Daoist deities (such as Yin Zhenjun, Lao Jun, and the Supreme Lord) who emphasize cultivation essentials, all stressing the importance of "refined contemplation," "purity," and "guarding authenticity."

The concrete methods of cultivation include:

Visualizing three divine beings in the "Chamber of the Cavern" (referring to the upper Dantian [energy center] between the eyebrows): contemplating Bai Yuanjun on the right leads to immortality, Huang Laojun at the center grants longevity, and Wu Yingjun on the left bestows supreme essence. Simultaneous vision of these three deities enables daytime ascension.

Practitioners must observe these prohibitions:

• Avoid obstructing cultivation through worldly desires like attachment to life/death, sensual pleasures, drunkenness, heterodox arts, or wealth
• Refrain from excessive pursuit of material possessions or physical adornment
• Resist following vulgar trends or believing slander
• Maintain physical and mental purity

The scripture concludes by emphasizing that true understanding of Daoist cultivation is rare—one must practice diligently as Laozi advised: "Superior students hear of the Dao and diligently practice it." The Great Cavern Scripture's value lies in containing the most refined cultivation secrets. Mastering the visualization of Wu Ying and other deities in the Chamber of the Cavern through refined contemplation holds the key to attaining immortality.

This scripture describes the different conditions and cultivation methods for attaining immortality through Daoist practice. The teachings are divided into several levels:

The first category comprises those with innate celestial endowments, born with ten extraordinary characteristics:

1. Their names are recorded in the celestial golden registers and jade tablets

2. Their immortal status is documented in the Palace of Supreme Mystery (Taiyuan Gong)

3. Mystical writings appear on their left palm

4. Blue vein patterns resembling the constellation Hekui mark their back

5. Their body bears the imprint of the Big Dipper

6. Purple light emanates from their crown, illuminating their internal organs

7. Their gait resembles a crane in flight or dragon's movement, with visible meridian patterns

8. Their heart has nine orifices and lungs contain blue acupoints

9. Five-colored cloud qi rises from their head to connect with heaven

10. Their speech resonates like metal and stone, with purple qi exhaled from the mouth

Such individuals are destined for immortality without deliberate cultivation.

The second category includes cultivators of lesser endowment:

• Those born in blessed lands
• Individuals with extraordinary bone structure
• Those whose virtue surpasses ancient sages
• People whose moral character equals the worthies
• Practitioners wholly devoted to the Dao with profound insight
• Those accumulating hidden virtue through Dao-aligned conduct
• Persons of pure heart-nature, gentle and benevolent

These may attain immortality through dedicated practice.

The third category achieves immortality through merit accumulation:

• Seven generations of virtuous ancestors
• Personal diligent cultivation without respite
• Ancestral connections to immortals
• Accumulation of three hundred good deeds

Fulfilling these conditions also leads to immortality.

Essential cultivation principles are emphasized:

1. Those with innate immortal bones inevitably have celestial affinity

2. Transmission of Daoist methods requires careful selection of recipients

3. Key practices include:

• Morning salutations facing east at sunrise
• Inner vision meditation with breath regulation and swallowing saliva
• Visualizing the White Primordial Lord (Bai Yuanjun), a body deity residing in the Scarlet Palace (heart center)
• Midnight practice during Jiazi days with loosened hair and powdered face
• Cross-legged sitting with breath regulation and invocation of body deities' names

The text reveals these teachings originated from Lord Lao's Outer Scripture of the Yellow Court (Huangting Waijing), transmitted to the author by immortals as essential cultivation secrets.

This scripture recounts a Daoist practitioner's personal experience in cultivating the "Chamber of the Cavern" (Dongfang, an internal alchemy term referring to a specific meditation area in the head). During practice, he would massage his eyes fourteen times with both hands while maintaining complete silence, avoiding external disturbances and emotional fluctuations. After five years of dedicated cultivation, he successfully visualized the form of the White Origin Lord (Baiyuan Jun, a Daoist immortal) within this chamber.

Later, while traveling through the sacred mountains of the Five Peaks, he encountered several immortals who transmitted secret teachings to him. At age seventy on Mount Song, he met the Yellow Elder Lord (Huanglao Jun, a venerated Daoist deity) and earnestly sought instruction. The Yellow Elder Lord revealed that seeing the White Origin Lord indicated a solid foundation, but to attain the state of a Perfected Being (Zhenren), he must continue cultivating the "Flowerless One" (Wuying, another crucial meditation locus). Though his request for the Scripture of the Chamber of the Cavern (Dongfang Jingjue) was not granted, the deity affirmed his noble spiritual destiny (Jinge Yuming, the "golden register and jade name" signifying preordained immortal potential), assuring him of eventual enlightenment.

The text emphasizes four key requirements for successful cultivation: 1) specific massage techniques, 2) a purified environment, 3) concentrated mental focus, and 4) sustained long-term commitment. It also reflects core Daoist principles—the importance of lineage transmission, gradual progress through stages, and the belief in predestined spiritual affinity with the Dao.

Commentary on the Inner Scripture of the Cavern Chamber by the Most High

The Sovereign Lord Huang-Lao (a revered Daoist deity, the Central Dao Lord) states: Huang-Lao Jun governs the central Dao and resides at the heart of the Cavern Chamber’s divine gate within the Cloud Court Palace. His divine name is Bo Tao, embodying what is known as the Great Sovereign’s Dao.

In the celestial realm, there exists a sacred palace called "Tai Xuan Dan Ling"—the dwelling of the Celestial Emperor. Also known as the Taiwei Palace, Purple Palace, Cinnabar Platform, or Numinous Palace, it is where the August Heaven’s Supreme Deity resides. Correspondingly, within the human body lies the Cavern Chamber (a key point in head cultivation), hence the initial explanation of the Purple Palace and Cinnabar Numinous concept.

The heavens contain the Jade Chamber of the Great Hall within the Cloud Court, where Huang-Lao Jun resides at its center. In the body, the Jade Chamber (a crucial head acupoint in cultivation) at the heart of the Cavern Chamber is also called the Purple Chamber, Crimson Palace, or Bright Hall. Above it is the Canopy (the crown of the head), with palace halls to the east and west, connected on either side to the Yellow Court (the Dantian region).

During cultivation, one gathers Qi at Kunlun (the head), making it lofty and stable. The Purple Chamber Cavern connects to the head—both elevated and profound—symbolizing the southern Mystic Garden and Yellow Chamber of Mount Kunlun. To its south lies the Cavern Gate Chamber, also called the Gate of the Cavern. As this text primarily discusses cultivation in the Purple Chamber, it first emphasizes the head’s significance.

The Golden Hall and Jade Citadel Where Immortals Dwell: Within the Cavern Chamber are a golden citadel and jade chamber—interconnected numinous palaces where mysterious radiances intertwine, serving as the abode of the Three Elders of Immortality. This cultivation area spans roughly three inches (referring to the upper Dantian region). Inside the Purple Chamber, a yellow gate links to the center of the Yellow Court, while a purple gate leads to the most refined and profound mysteries.

Cultivation Method: When transmitting this scripture, first observe purification rites (Daoist rituals for bodily and mental cleansing). Disciples must reverently kneel to receive the teachings and continue purification afterward. After three months of cultivation at Mount Shaoshi, ascend Mount Taishi, enter the Cavern Gate, and pay homage again to Huang-Lao Jun. He then imparts the Inner Scripture of the Cavern Chamber, instructing disciples to sit in silent meditation at midnight, silently reciting the scripture to behold Lord Wu Ying (a key guardian deity). Persist in practice for twenty-seven years, and one may simultaneously perceive both Lord Wu Ying and Huang-Lao Jun, ultimately receiving the Great Cavern True Scripture and ascending to immortality astride clouds and dragons. This scripture is profoundly esoteric—transmit it with caution, never to the unworthy.

The Commentary on the Inner Scripture of the Supreme Cavern Chamber describes the mystical realms of inner cultivation within the human body. The text primarily explains:

Within the head (termed the "cavern chamber"), there exists a crucial region—the left side houses the Azure Palace where the Azure Lad (Lord of Nine Elders) resides, while the right contains the Bright Purity Mansion inhabited by the White Jade Maiden (Mother of Western Purity). By consistently visualizing and contemplating these two sacred spaces, one may attain immortality and realize the Dao.

Within the cavern chamber dwell two even more significant divine beings: on the left is Lord Wuying (also known as Lord Yuansu or the Divine Prince), and on the right is Lord Baiyuan (also called Lord Dongyang). Both are supreme deities, and by single-mindedly cultivating and contemplating them, one may achieve genuine realization of the Dao.

These divine beings emerge spontaneously from formless transformation, parentless in origin. The most exalted among them is the Imperial Essence Yuansu Great Lord of the Dao, who exists in solitary perfection, preceding even the Great Void. Practitioners must maintain constant contemplation day and night without negligence.

Lord Wuying wears a radiant crown, rides a purple divine canopy, and adorns himself with flowing golden bells. The practice method involves sitting cross-legged after midnight (when vital Qi is most vigorous), placing hands on knees, holding the breath while closing the eyes for inner vision, and silently reciting incantations to invoke divine protection.

Lord Baiyuan, in contrast, dons dragon-patterned robes and carries the Divine Tiger talisman. His cultivation method requires facing east at dawn to perform reverent bows, holding the breath for inner observation while silently chanting to request the deity's companionship in roaming immortal realms.

These divine beings all originate from the Yellow Chamber (i.e., the cavern chamber) and journey together with practitioners through the Dantian (lower energy center). By maintaining constant contemplation of these deities day and night, one will inevitably become a Zhenren (perfected being).

(Note: "Contemplation" [cunnian] refers to Daoist cultivation terminology involving visualization and silent recitation to commune with deities; "Yellow Chamber" and "cavern chamber" indicate specific cranial regions; "Dantian" denotes vital energy centers in the body.)

This scripture elucidates Daoist meditation techniques for visualizing deities (cunxiang) and describes the locations and functions of key energy centers within the body:

The "Dongxuan Cavern" refers to the divine chamber in the head, which connects with the celestial Palace of the Great Subtlety Emperor. By visualizing the deity Wuying Jun (Lord of No-Form Heroism), one comprehends the profound truths of the Dadong Zhenjing (Great Grotto Scripture of Truth). Encountering Baiyuan Jun (Lord of White Origin) signifies attainment of immortal Dao. Wuying Jun embodies elemental purity, while Baiyuan Jun represents the path of celestial transcendence.

Taojun (the Great Dao Lord), clad in vermilion robes and purple crown, resides in the Mingmen (Gate of Life) within the Dantian region. During practice, one must harmonize the Qi of the six directions (cardinal and vertical axes) with these divine presences. Huangning, the deity dwelling one inch above the midpoint between the breasts, is invoked by tapping teeth fourteen times at dusk while reciting incantations to regulate Jing (essence) and Qi in the yellow chamber.

"Summoning Yang and beckoning Yin" refers to mobilizing these complementary forces: Yang denotes the Three Supreme Yang Qi, while Yin represents the Three Yin Qi. The Liuding (Six Ding) are six celestial warrior goddesses. Invoking Yang brings the three Yang energies descending, summoning Yin causes three dragons to ascend, and commanding the Liuding manifests these divine maidens. Detailed methods are recorded in the Laojun Jing (Scripture of Lord Lao).

The "undifferentiated primal vista" signifies returning to original Yang (primordial Yang Qi). The Three Ones (deities of the upper, middle, and lower Dantian) constitute vital divine presences. Baiyuan Jun converges with primordial Yang Qi in the Dantian. Among the three subtle palaces—the Niwan (Mud Ball) Palace in the head, Jianggong (Crimson Palace) in the heart, and lower Dantian—the Jade Chamber (Dongfang Palace in the head) holds the most refined essence.

The Dongfang Palace contains supremely refined deities of absolute purity that generate Shangyuan Qi (primordial energy). Practitioners who perceive these deities attain daylight ascension to the Taiji Palace in the Great Subtlety Heaven—flanked by the Hall of Perfected Beings on the right, Wuying Jun's abode on the left, and Baiyuan Jun's residence on the right.

The text concludes by emphasizing that when essence and Qi circulate unobstructed and deities manifest, the Three Pure Qi (San Su) transforms into auspicious clouds that permeate the six directions, achieving perfect harmony among the three Dantian's energies.

This passage describes the visualization methods (cunxiang) and incantations used in Daoist Neidan (internal alchemy) practice:

When a practitioner's Jing (essence), Qi (vital energy), and Shen (spirit) — the Three Treasures — become abundant within the body, they manifest as three-colored clouds (the Three Primordial Mists). When the practitioner's consciousness expands to connect with the six directions of space (heaven, earth, and the four cardinal directions), they can resonate with the energies of Yin-Yang and summon divine dragons. Riding these misty clouds while astride celestial dragons marks the conditions for achieving immortality.

The "purple-jade canopy" refers to the violet energy field forming above the adept's head, while the "immortal palaces" denote the celestial realms of the Supreme Pure Ones. At advanced stages of cultivation, jade maidens (celestial beings) will guide the practitioner to ride clouds and dragons to these heavenly palaces, thereby attaining true immortality.

The text particularly emphasizes that these cultivation methods must be transmitted with caution and should never be carelessly taught to unworthy individuals.

Specific cultivation techniques:

1. Visualize five-directional cloud energies at dawn, noon, and sunset:

• Eastern azure clouds transform into Azure Dragons
• Western white clouds transform into White Tigers
• Southern crimson clouds transform as Vermilion Birds
• Northern black clouds transform as Dark Warriors
• Central yellow clouds merge with one's own form

2. The morning incantation conveys:

Praise the subtle vastness of primordial Qi, allowing the spirit to soar freely. Maintain an expansive and serene heart-mind, clear as the bright moon. Through regulated breathing, commune with divine beings.

3. The evening incantation expresses:

Unhindered communion with deities, partaking of immortal herbs and lingzhi mushrooms. Riding the Yao constellation as steeds and the Jade Balance stars as chariots to roam heaven and earth. All ailments cured, with vibrant spiritual energy. Protected by the Great Unity deity and guarded by divine spirits.

Important guidelines:

• Maintain pure mental focus while reciting toward the imperial direction
• Alternatively recite according to temporal and directional correspondences
• Those wearing Fulu (talismans) must establish covenants with heaven and earth
• Practitioners violating the rules will face retribution
• Recitation is prohibited on Wuchen and Wuxu days (specific lunar calendar dates)

This scripture originates from the ninth volume of the Zhengyi Xuandu Code, containing essential cultivation instructions transmitted by Lord Lao (the deified Laozi).
