Yogini Tantra is the most important tantra of the Bengali-Assamese tradition of the “left hand”, which in many ways continues the line of the Kalika Purana that appeared several centuries earlier. Yogini Tantra was compiled in the 16th century. in Assam, which has been the center of worship of the Goddess since ancient times. The word “yogini” itself can have several meanings, being both one of the names of the Goddess and the name of the younger female divine entities that make up her retinue, as well as women who practice magic and/or yoga. The work consists of two sections. Several chapters of the first section are devoted to the prescriptions of tantric magic. In addition, it contains information about various types of sadhana (religious practice of tantrics), including the famous ritual of the five “Ms”. The uniqueness of the first section is given by the fact that a significant part of it is occupied by a mythological narrative (for example, it tells about the duel of the Goddess with the demon Ghora, in whose guise her husband Shiva is embodied), which is completely atypical for tantras, and many of the legends contained here are of a completely unique nature. The second section of the Yogini Tantra is a geographical description of the holy places of Kamarupa.
