Everyone is attracted to the Path of Deliberate Rigour. In the broad sense this path includes asans, bandhas, mudras, silence (moun), hathayoga in the ordinary sense, control over sexual desire, tratak and pranayam. Though these topics appear to be associated only with the physical body, yet how beneficial they prove from the psychological and spiritual viewpoints, as well as their limitations in bringing about spiritual evolution are discussed in this holy book.
