Tantric sex or sexual yoga refers to a range of practices in Hindu and Buddhist tantra that utilize sexual activity in a ritual or yogic context. Tantric sex is associated with antinomian elements such as the consumption of alcohol, and the offerings of substances like meat to deities. Moreover, sexual fluids may be viewed as power substances and used for ritual purposes, either externally or internally.[1][2]
The actual terms used in the classical texts to refer to this practice include "Karmamudra" (Tibetan: ལས་ཀྱི་ཕྱག་རྒྱ las kyi phyag rgya, "action seal") in Buddhist tantras and "Maithuna" (Devanagari: मैथुन, "coupling") in Hindu sources. In Hindu Tantra, Maithuna is the most important of the five makara (five tantric substances) and constitutes the main part of the Grand Ritual of Tantra variously known as Panchamakara, Panchatattva, and Tattva Chakra. In Tibetan Buddhism, karmamudra is often an important part of the completion stage of tantric practice.
While there may be some connection between these practices and the Kāmashāstra literature (which include the Kāmasūtra), the two practice traditions are separate methods with separate goals. As the British Indologist Geoffrey Samuel notes, while the kāmasāstra literature is about the pursuit of sexual pleasure (kāmā), sexual yoga practices are often aimed towards the quest for liberation (moksha).[3]
