If you have made love to a woman or to a man, and the love was really total and orgasmic, you forget who you are. It is mindblowing. You simply don’t know who you are. In a certain moment of deep orgasmic bliss, oneness happens. That is the whole effort of Tantra: to transform sex into an experience of oneness — because that will be your first experience of oneness, and enlightenment is the last experience of oneness.
