A notable feature of some "left tantra" ascetics was their pursuit of siddhis (supernatural abilities) and "bala" (powers), such as averting danger ("santih") and the ability to harm enemies ("abhicarah"). Ganachakras, ritual feasts, would sometimes be held in cemeteries and cremation grounds and featured possession by powerful female deities called Yoginis. The cult of Yoginis aimed to gain special powers through esoteric worship of the Shakti or the feminine aspects of the divine. The groups included sisterhoods that participated in the rites.
