Karmamudrā (Sanskrit; "action seal," Tibetan: las-kyi phyag-rgya; commonly misspelled as: kāmamudrā or "desire seal") is a Vajrayana Buddhist technique which makes use of sexual union with a physical or visualized consort as well as the practice of inner heat (tummo) to achieve a non-dual state of bliss and insight into emptiness. In Tibetan Buddhism, proficiency in inner heat yoga is generally seen as a prerequisite to the practice of karmamudrā.
