Explaining the Calling of the Names of Deities when Deploying the Army to Enter the Great Yin

Great YinOriginal: Taiyin. In military divination, this represents a position of concealment, stealth, and celestial protection. By "entering" the Great Yin, an army was believed to become invisible to the enemy or shielded by divine forces.

The Classic of the Three Primes states: If you wish to deploy the army, you should face the appropriate direction and call the name of the deity of that direction. Then, walk sixty paces and turn left to enter the Great Yin.

The Six Ding A group of six Daoist spirits (the "Jade Maidens") associated with the Yin aspects of the sexagenary cycle, often invoked for protection and invisibility. are also called the Great Yin; all of these are the same.
