White, Red, Black Tantra

White tantric yoga should not be confused with black or red tantric. These forms of yoga also transform energy, but in a different way and for different purposes. Black tantric directs the energy to manipulate another human being, and red tantric directs the energy for sexual purposes http://kundaliniyoga.tribe.net/thread/b96cce30-e840-46d8-855e-5781c364c39e
