India, ca. 1350
A text of twenty-eight chapters, the authorship of which is unknown. To a great extent the text deals with the worship of the goddesses Kali and Kamakhya. It describes the Yonimandala in the Yoni Pitha and other sacred sites and temples known as pithas where the goddess is worshipped, and especially those where worship is supposed to have especially excellent results.
The text has a number of recommendations concerning the five makara and about who may perform sexual rituals with whom, forbids incest between mother and son; and also gives examples of Tantric visualization.
Like many other Kula-inspired texts, the Yogini Tantra advocates the moral codes of mainstream Hinduism to be broken and suspends many of the usual prohibitions concerning inter-marriage between members of different castes. It allows women to speak up to everyone and to have intimate relationships with whom they please.
The Yogini Tantra includes, in chapter VI, a good example of a Tantric Visualization.
In this case a male devotee is asked to imagine a
sixteen year old woman with a luster like that of a great many suns which
is to be fancied from her head to breasts. Thus reflecting, one should concentrate on her
figure from her yoni to the lowest portion of her feet.
That figure is to be contemplated as adorned with ornaments.
Chapter VIII describes the origin of the yoginis which are stated to have come into being out of the wavicles (particle/wave paradox as in light) of Kali's energy.
