A ganacakra is also known as tsok, ganapuja, cakrapuja or ganacakrapuja. It is a generic term for various tantric assemblies or feasts, in which practitioners meet to chant mantra, enact mudra, make votive offerings and practice various tantric rituals as part of a sādhanā, or spiritual practice. The ganachakra often comprises a sacramental meal and festivities such as dancing, spirit possession, and trance; the feast generally consisting of materials that were considered forbidden or taboo in medieval India like meat, fish, and wine. As a tantric practice, forms of gaṇacakra are practiced today in Hinduism, Bön and Vajrayāna Buddhism.
