《女丹合編》Vol. 15

The Compilation of Female Alchemy (Nüdan Hebian) is a secret manual of female Neidan (internal alchemy) practice composed by the Qing dynasty Daoist Chen Yongqing (Daoist name Wuxinzi). It details the unique methods for women's cultivation, which differ significantly from men's practices due to physiological distinctions.

The crux of female cultivation lies in "beheading the crimson dragon" — a specialized technique to cease menstruation through energetic practice. Since menstrual flow depletes primordial Qi, practitioners must use focused intention coordinated with reverse breathing (inhaling while contracting the abdomen) to reverse the menstrual essence upward, akin to forcing the Yellow River's current to flow backward. During menstruation, one concentrates the spirit on the lower Dantian (energy center), redirecting the vital essence like severing a dragon's head with a blade.

Key considerations in practice include: First, maintaining mental serenity to allow the body's Yang energy to arise naturally. This resembles planting the golden crow (sun) within the moon, facilitating Yin-Yang union. Second, skillfully regulating the "firing times" — alternating between gentle "civil fire" breathing and vigorous "military fire" respiration without disturbing the Shen (spirit). When sensing the stirring of true Qi, immediately guide it back to accumulate as a "sacred embryo" (nascent elixir) within the breast region.

Successful "dragon beheading" brings marvelous transformations: during meditation, one experiences ambrosia-like fluids flowing from the Ziwei Palace (upper Dantian) throughout the body, creating euphoric sensations. Persistent practice eventually forms the sacred embryo in the breasts, achieving rejuvenation. Legend states that after seven days, the practitioner regains the primordial Yang state, after which cultivation methods align with male practices.

Critical warnings accompany these techniques: personal instruction from an enlightened master is essential due to individual variations. Practitioners must vigilantly guard against essence leakage (metaphorically described as "preventing the yellow tiger from scaling walls") while precisely applying the firing process (breath and intention) for refinement. Like simmering medicine, this follows the principle of "mending bamboo with bamboo" — gathering essence back into the dual breasts through sympathetic resonance.

This scripture reveals the essential methods and precautions for women practicing Neidan (internal alchemy) cultivation.

The crux of practice lies in maintaining a clear and unconfused spirit, akin to wielding the sword of detachment to sever emotional desires (the "red dragon" symbolizes passions)—only then can one manifest true attainment. At advanced stages, female practitioners may achieve immortality like legendary female transcendents Cai Luan and Yun Qiao. However, this demands unwavering resolve as arduous as growing lotuses in fire, coupled with nurturing compassion, to ascend from ordinary ground to immortality.

Though the Golden Elixir (the refined essence obtained through cultivation) is but millet-sized, its sweetness rivals honey and can revive the dead. Yet ordinary people seldom perceive its marvels—it requires master-disciple transmission, for this elixir inherently resides within one's own being.

Women cultivators must meditate with single-minded focus, eliminating selfish desires and distracting thoughts, lest they lose their "true lead" (primordial Qi). Guard this vital energy vigilantly; if leakage occurs, apply vigorous methods to retrieve it. Those lacking steadfast virtue are unfit for practice, being prone to ridicule or divine secrets' exposure.

Special admonitions for female practitioners: the temperamentally restless should abstain; never discuss cultivation casually; beware false masters; sometimes, remaining a devoted daughter-in-law may secure rebirth in pure lands. The text ultimately cautions women against forced pursuit of the Dao—unrestrained passions invite disgrace, and maidenly modesty should be cultivated young.

This passage reflects classical rigor toward female cultivation, emphasizing purity of heart, secrecy, and discernment against false paths, while revealing conservative attitudes toward women's spiritual aspirations.
