Even though you may have already been introduced to yoga, it is necessary to know something about tantra also. Since the dawn of creation, the tantrics and yogis have realised that in this physical body there is a potential force. It is not psychological or transcendental; it is a dynamic potential force in the material body, and it is called Kundalini. This Kundalini is the greatest discovery of tantra and yoga. Scientists have begun to look into this, and a summary of the latest scientific experiments is included in this book.
