Tantra, an exposition of Sri-vidya, is a thread of Vedic tantu. This ray of the light of consciousness folds upon itself as a coil (kundala) forming the coiled energies of the conscious universe, thus becoming kundalini. This volume, while portraying kundalini from its psycho-physical and spiritual implications and impacts, tries to alleviate some misconceptions about the nature of cakras - the consciousness centres. It deals at length with the phenomena of higher levels of spiritual evolution raising the kundalini and opening the cakras - helping one drop all mental habit patterns to achieve liberation. This book is a must read for the practitioners of Yoga and all who want to take their spiritual life to a new realm.
