Tantra

Tantra is that Asian body of beliefs and practices which, working from the principle that the universe we experience is nothing other than the concrete manifestation of the divine energy of the godhead that creates and maintains that universe, seeks to ritually appropriate and channel that energy, within the human microcosm, in creative and emancipatory ways. (David Gordon White - Tantra in Practice) Tantras are divided into Hindu Tantra Buddhist Tantra Jain Tantra even though there is an overlap between these schools.
