《天皇太一神律避穢經》

Interpretation of The Scripture of Celestial Sovereign Taiyi's Divine Precepts for Avoiding Contaminations

In the celestial palaces of the heavens, the immortals emphasize avoiding divine taboos to nurture life and govern the state, while in the human realm, cultivation requires steering clear of worldly impurities. Specific methods for averting contamination include: using precious talismans (Daoist fulu) and fire rituals to dispel celestial defilements, refining elixirs to avoid contamination from rivers and lakes, employing swift-flying talismans to command spirits and ward off pollution from childbirth, and establishing protective boundaries to shield against solar and lunar impurities. These primary taboos are generally arranged as follows.

In the practice of immortality and elixir refinement, there are 3,720 prohibitive methods—adhering strictly to these rules ensures flawless success. Among them, twelve major contaminations are most critical. If elixirs are refined during forbidden times, they will never succeed. For instance, the Yellow Emperor’s alchemical taboos included the chen year, month, and day (Dragon year, month, and day), the zi year, month, and day (Rat year, month, and day), and other zodiac-corresponding times—all unsuitable for alchemical work.

Specific prohibited circumstances include:

1. When purple clouds first gather and the Dragon-Tiger forces clash, thunderous days are unfit for elixir refinement.

2. During solar or lunar eclipses, furnace ignition is forbidden, and protective boundaries must also avoid these hours.

3. Celestial Dragon Convergence Contamination: Elixir refinement is prohibited on chen days (Dragon days) in the first and last ten days of the third lunar month.

4. Big Dipper Displacement Contamination: When the Dipper’s handle points to the yin position at dawn in the first lunar month, or when the Dipper vanishes, elixir work is taboo.

5. Azure Heaven Dragon Convergence Contamination: When crimson clouds or dragon-shaped formations appear in the sky, sealing the furnace is forbidden. If Jupiter (Taisui) resides in the mao position (Rabbit year) while its spirit manifests in the shen position (Monkey position), it is also inauspicious.

6. Earthly Vein Contamination: Ancient tombs, waterless lands, sites of debauchery, birthing rooms, dragon lairs, ancient pools, ruins of old cities, foundations of abandoned temples, former marketplaces, ancient shrines, old prisons, and disused kilns must never serve as elixir-refining sites.

7. Heavenly Meteor Contamination: Places once inhabited by ancient sages and immortals are unsuitable for alchemy.

8. Yin-Yang Convergence Contamination: Spring’s ding-mao days, summer’s jia-wu days, autumn’s geng-shen days, and winter’s ren-gui days are forbidden for elixir work.

9. Jade Maiden Patrol Contamination: All liuding days (dates marked by "Ding" in the sexagenary cycle, associated with the Six Ding Jade Maidens in Daoism) are prohibited for alchemy.

10. Celestial Anomaly Contamination: When morning clouds fill the sky, elixir refinement must cease.

11. Demon Battle Blood Contamination: If stone drums sound spontaneously or subterranean thunder is heard, elixir refinement is forbidden for seven days—otherwise, the medicine’s potency will dissipate entirely.

(Note: Terms like chen day or zi day refer to the Earthly Branch calendar days, corresponding to zodiac days; "Six Ding Days" are special Daoist timekeeping designations for days containing "Ding" in the 60-day cycle.)

This scripture details essential taboos to observe during elixir preparation:

Whether refining major Golden Elixirs (Jindan) or minor ones, all medicinal ingredients must be rigorously protected from defilement. The Daoist Seal of Elixir Radiance should be stamped upon the workshop and tools, which must then be coated with specially prepared medicinal clay. Under no circumstances should the five pungent vegetables (onions, garlic, leeks, shallots, and asafoetida), postpartum women, poultry, or dogs enter the alchemical workspace.

The repeated admonition to "exercise utmost caution" underscores how these purity regulations form the sacred foundation of alchemical practice. These divine ordinances established by the Celestial Sovereign Taiyi (a supreme Daoist deity) serve to maintain the ritual purity of the alchemical environment, preventing external contamination that could compromise the elixir's potency.
