Tantra originated over 6,000 years ago in India as a way to use sexuality to enhance spiritual enlightenment, viewing sex as a sacred act between partners. It focuses on prolonging intimacy and using orgasmic energies for heightened awareness. There are three types of sexual energies in Tantra - Tamasic (passive), Rajasic (passionate), and Sattvic (meditative and spiritual). Tantric sex aims to merge both partners physically, mentally, emotionally and spiritually through techniques like being fully present, open-hearted, egoless and merging with the divine.
