Professor Miranda Shaw summarises the experience of a ganachakra: The feast is an esoteric ritual that unfolds in many stages. The sacred space for the ceremony is demarcated by geometric designs drawn on the ground with powdered pigments, and an elaborate array of offerings and foods are laid out. The participants don special insignia like bone ornaments and crowns and use musical instruments of archaic design... for inducing heightened awareness. Practitioners sit in a circle and partake of sacramental meat and wine served in skull-cups.The feasts also provide an occasion for the exchange of ritual lore, the ritual worship of women (sripuja), and the performance of sexual yogas. The feast culminates in the performance of tantric dances and music that must never be disclosed to outsiders.
