There are a few things that you have to understand—I cannot give any proofs for them, they are beyond proofs. Only your experience will give you the proof. For example, the biological organism is capable of transcending itself. It transcends in certain moments. Those are the moments most cherished in the human mind, because in those moments you have known freedom, an expanded self, an utter silence and peace; love without its counterpart, hate, following it. That moment we call orgasm.
Biology gives you orgasm; that is the most precious gift from blind biology. You can use those moments of freedom, melting, disappearing, for meditation. There is no better space from which to jump into meditation than orgasm. Two lovers feeling one soul in two bodies … everything has stopped for the moment, even time has stopped. There are no thoughts, the mind has stopped. You are in your simple isness. Those are the little spaces from where you can get beyond biology. All that you have to know is that this is what meditation is: timelessness, egolessness, silence, blissfulness, an all-pervading joy, overwhelming ecstasy.

Osho points to a human experience that most religions not only avoid but condemn and that is sexual orgasm. Osho teaches that sexual orgasm is a small taste of meditation.
Ecstasy can be achieved in other ways but the most biologically fundamental is sexual arousal and then orgasm. Why are most religions so prudish and judgmental when it comes to sexual activity? It is because religion can’t control the experience, and the experience takes one away from religion into the realm of spirituality if one is awake and aware? With the ecstasy of altered consciousness who needs religion? Who will leave the conjugal bed and go to church? Spiritual experience is in the conjugal bed not in a building listening to a clergy person drone on about mundane religious concerns.
Back in the 60s there was an expression, “Make love not war.” If this were actually true, wouldn’t the world be a better place?
