Written by a leading authority on Shaktic and Tantric thought, this book is considered the prime document for study and application of Kundalini yoga. It probes the philosophical and mythological nature of Kundalini; the esoteric anatomy associated with it; the study of mantras; the chakras, or psychic centers in the human body; the associated yoga and much, much more. Two important Tantric documents are included: The Description of the Six Chakras and Five-fold Footstool.
