The Hundred-fold Purifying Pills

Regarding the various methods of binding mercury mentioned in the Ṛddhikhaṇḍa Section on Success, I will now describe the method of body-transmutation.

The Method of Gradual Perfection

Regarding the gradual perfection mentioned in the Manthana Bhairava a tantric text: (197) For this purpose, perfect the five elements and the sixth, the soul. At the time of the flow of kākinī a female energy/spirit, engage in union and gather the essence. (198) That seed-fluid in the yoni is known by the wise as the sky. The union with the son born of the kākinī is called the path of life. (199) The fire is the flower of the kākinī, the water is the son's blood. The entire body of the son of the kākinī is called the earth element. (200) The potency arising from the body of the mercury-practitioner is called the soul. Having combined one karṣa of each with mercury, the wise should preserve it, well-ground and formed into a ball. (201) Make it as tall as a man and half as wide in a copper cauldron, about six fingers thick. (202) It must be held firmly on the back of a four-mouthed furnace. (203) Mix equal parts of cow ghee and human oil. Fill the cauldron with it and worship the perfected cycle. (204) Propitiate the maiden, the teacher, the gods, the fire, Bhairava, and the followers of Bhairava. Offer sacrifices and worship the guardian of the field. (205) Perform the blowing fanning of the fire in the four directions slowly with four sparks from charcoal of khadira Acacia catechu. (206)
