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.
Let each one of us pray day and night for the downtrodden millions who are held fast by poverty, priestcraft, and tyranny. Pray day and night for them. I care more to preach religion to them than to the high and the rich.
-Swami Vivekananda
