The holy places associated with the Mother Goddess and spread over various parts of the indian subcontinent have been popular pilgrim spots for a long time. According to some late Tantric texts ascribable to Eastern India, the number of such Sakta-Tirthas is fifty-one and the present monograph is a dissertation on the origin and development of this conception. Thus it is at the same time the study of a number of Tantric and other texts as well as of certain problems of Tantric religion and of historical geography. It is unique in its approach because Tantra Studies have not progressed satisfactorily so far on scientific lines.
