The Cakrasaṃvara Tantra (Tibetan: འཁོར་ལོ་བདེ་མཆོག, Wylie: 'khor lo bde mchog, khorlo demchok, The "Binding of the Wheels" Tantra) is an influential Buddhist Tantra. It is roughly dated to the late eighth or early ninth century by David B. Gray (with a terminus ante quem in the late tenth century).
These are key deities in the Vajrayana system, uniting two of the most powerful ideas in esoteric Buddhism, wisdom, embodied in Vajravarahi, and compassion, the essence of Chakrasamvara. His name, which translates as Circle of Bliss, embodies the powerful union of these two fundamental tenets of Buddhism.
