Synopsis The Tantras can be both a fascinating and a frustrating study. There is a deliberate vagueness about them, and even the authorities are found to mislead. The erotic and occult involvements are needlessly brought into focus in recent publications. Here is an attempt to explore the psychological bases of the general Tantrik ideology.  The author has tried to reconstruct the Tantrik system in terms of Yantra and Mantra. He has emphasised the value of Tantra for contemplative success and for personality reintegration. The book is an authoritative and explanatory. The illustrations are traditionally accurate and original.
