Reprogramming the psyche is futile. You just replace one set of preconceived notions with another. Meditation dissolves preconceptual condition. It's probably better to 'transcend' the things that are no longer useful to you than to expend energy trying to 'delete' them. Sex, drugs, or rock-and-roll might also decrystallize to a limited degree but not nearly as efficient and effective as meditation. Warning. The more 'holisitically' aware you become, the more crazy you sound to most people when you speak.
