Chinachara-tantra

«Chinachara-tantra» — a sacred text of the tantric tradition dedicated to the cult of the goddess Tara, revered in both Hinduism and Buddhism.
The place of origin of the text is most likely Bengal or Assam, where the cults of fierce... female deities have been widespread since ancient times. The tantra narrates that the sage Vasishtha, having failed in his ascetic practices, turns to Vishnu in the guise of Buddha, who proclaims to him the precepts of the path of chinachara. The foundation of this path consists of transgressive practices, including the worship of woman as the embodiment of the Goddess.
The translation is accompanied by a preface, commentary, and a glossary of subjects and terms.
