I did Tai Chi lessons for a while, and enjoyed the "charging up with chi/The Force" feeling it would give me, from pucturing flows of energy throught the body and such. Of course the "real" cause of those positive feelings are extra blood oxygenation, meditation, clearing extraneous thoughts, etc.

I was OK with this disconnect between the map and the territory, because there was a linkage between them: the deep breathing, mental focusing, and let's not forget the placebo effect.

I suppose this is not too different in principle to the "mind hacks" bandied about around here.
