I think Tantra like a lot of thinks is open to interpretation. You can get very rigid interpretations and you can have a more liberal way of Tantra. As one who has gone in for Tantra a lot in recent times I must say that its great when done by a practioner who practices Tantric type living and in that respect I have been lucky. Yes the breathwork is a big part of it and the touch of the massage giver too. Also the backgroynd music and the ambience of the room.
