We have been practicing since 1987 and teaching since 1997. We have authored 4 published books on Tantra, sacred sex, and relationships. There is no certification or registration from any organization authority that is recognized or regulated. Some established teachers of neo-Tantra in the west, like Margo Anand and Charles Muir conduct Tantra teacher training programs. Some teachers claim the legitimacy of a spiritual lineage dating back hundreds or even thousands of years, the teaching of which is passed on from guru to disciple, one-on-one, (like Daniel Odier and John Mumford), but we do not. For the most part we are self taught lovers, through our own experiences. But we have also studied with some great teachers like Daniel Odier—who is a traditional Tantra master (not at all related to sex) and with Paul Welsh who was a long time disciple of Osho.
