The cakras are centres in the subtle body, usually counted as six or seven, from the base of the spine to the crown of the head, each associated with an element, a sound and a deity. Kuṇḍalinī rises through them in tantric yoga. The systems differ between texts; the familiar seven-chakra scheme became standard relatively late.
