This book deals with all the essential and positive aspects of the Tantra tradition in India. It is one of the most authoritative books written on the Tantras.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies; but the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
-Swami Vivekananda
