If you've spent any time in the world of sacred sexuality, you've heard the word tantra. It gets thrown around a lot. Mostly incorrectly. In the West, "tantra" has become a catchall for anything that combines sex and spirituality — slow sex, breathwork during lovemaking, maybe some candles and eye-gazing. And while none of that is bad, it's not what the Tantric masters of India were talking about. Not even close.
