What is Yoni Tantra?

The Yoni Tantra is a religious text from Bengal (16th century) mainly concerned with describing the Yoni Puja, or "Mass of the Vulva"; one of the secret and esoteric Tantric rituals dedicated to creating - and consuming - the sacred fluid which is called yonitattva.

According to this text, sexual union (mithunam) is an indispensable part of Tantric ritual and may be performed by and with women between the age of twelve and sixty years, married or not, except for a girl not yet menstruating. The text specifies nine types of women (navakanya) who may perform sexual rituals, yet explicitly forbids an incestuous mother/son constellation.
