Tantra yoga is the union of the male and female energy within us, and the union of the spiritual nature and the nature of the world around us. The joining of those seemingly different aspects of their nature leads one to deeper spiritual evolution. That's not all. I would like to put an addendum on that. A lot of people think that Tantra yoga is about sex and it gets advertised that way a lot, which is false. Sex accounts about two percent of Tantra yoga. People need to do a little more research, a little more studying and talk to people who are really involved in yoga and not just interested in the marketing aspect of it.
