Gaṇacakra (tshogs kyi 'khor lo) is a ritualized feast in which the deities of a specific tantric system are worshipped as part of a group practice. [1] . Gaṇacakra creates a particular kind of maṇḍala, or ‘sacred ritual space’, for the practices of many higher tantras (mahā, anu - and ati-yoga, or niruttarayoga). [2] .
