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.
All who have actually attained any real religious experience never wrangle over the form in which the different religions are expressed. They know that the soul of all religions is the same and so they have no quarrel with anybody just because he or she does not speak in the same tongue.
-Swami Vivekananda
