The Ego Uses Both Sex And Meditation As An Escape

Question: Krishnamurti says that one craves sex, because in that, one finds no ‘me’, ego, and hence no conflict. And one uses it as an escape. Why does one not use, meditation too, as an escape? Is it because that one lacks understanding, energy, or is it because that the outside influences and inherent tendencies, acquired and hence biological, are too strong?
