This episode elucidates the final stage of the Siddha’s alchemical endeavors, which is known as reversal, or “ulata sadhana”. In reversal, the breath, mind, and seed of the human being are coagulated into a stable substance and directed into the subtle body to be transformed into the nectar of immortality. We look closely at the nature of this process and the specifics of the subtle body itself, which is found to be lunar in its nature: an ebb and flow of spirit and essence, coming into and passing out of being like the waxing and waning moon in its journey across the night sky.
