Thank you for this...just what I was looking for...great timing.
I agree with you Jacob, this way of presenting Tantra is so simplistic, using the word Tantra is a great way to make money.. Perhaps they could call what they are teaching as sacred sexuality or sacred relationship. Tantra originates in India, and most Tantrics are celibate advanced Yogi's, they have mastered the art and science of Auyveda, Jyotish, Vastu, Sanskrit, and Yoga..
Tantra doesn't mean partner based or sexuality based technique. It just refers to a level of technique, or a kind of school(eg Buddhist tantra, Hindu tantra, Baul tantra). Usually it has to do with meditation but I don't think it's separate from being out in the world. I think it's confusing and a misnomer to connect 'tantra' with couples practice, or sexual practice.
These are great ways for couples to connect on an almost "spiritual" level. Thank you much for the ideas, Yoga Journal!
