What is the purpose of practicing this yoga, or what is this teaching for? Who is qualified to practice it? How is the teaching of this Yoga exercised?
The person who practices this teaching, as well as those who practice the Transformation Yoga, must have well obtained the initiation and observed the Tantric precepts in a perfect manner, etc., as required in the practice of the Arising Yoga.
According to Tantra there are three different teachings of the Transformation practices: the special Transformation Yoga; the Teaching of the self-mind (or soul) entering into another's corpse; and the teaching of expelling another's soul from his body so that one's consciousness may enter this body.
