There is a subtler level to the sexual experience than the mere physical routine.
It is a level that is religious in essence. To understand this experience you must pay careful attention. If you cannot grasp the meaning of this experience, you will live and die in sex alone.
Lightning shines in the darkness of the night, but the darkness is not part of the lightning. The only relation between the two is that lightning only stands out at night, only in the darkness. And the same is true of sex. There is a realization, an exhilaration, a light that shines in sex, but that phenomenon is not from sex itself. Although it is associated with it, it is just a by-product. The light that shines in orgasm transcends sex; it comes from beyond. If we can comprehend this experience of the beyond we can rise above sex. Otherwise, we will never be able to.
You can liberate yourself from sex if you can learn to attain to samadhi without sex. If a man who wants an article costing one thousand rupees is shown where one can be had for free, he would not be in his right senses if he were to go to the market to buy it so expensively. If a man can be shown how he can attain the same ecstasy he derives from sex by some other means and in much greater measure, his mind will automatically cease its rush towards sex; his mind will start racing in the other direction.
Man had his first realization of samadhi in the experience of sex.
But sex is a costly affair, a very costly affair indeed. And it does not last for more than a moment; after a momentary climax, we return again to our original position. For a second, we reach towards a different plane of existence; for a second, we climb towards a peak of immense satisfaction. The momentum is towards the pinnacle, but we have hardly taken a step when we fall back to first base. A wave aspires to reach the sky, but it has hardly risen noticeably when it already starts to fall. We are the same. It is for that ecstasy, for that joy, for that realization, that we accumulate energy from time to time and again start the ascent. We almost touch that subtler plane, that higher realm, but again we fall back to our original position, minus a considerable amount of power and energy.
So long as man’s mind remains immersed in this river of sex he will repeatedly rise and fall again. Life is a continuous push towards egolessness, towards timelessness — whether conscious or unconscious. The intense desire of the being is to know its real self, to know the truth, to know the original, eternal, timeless source — to unite with that which is beyond time, to attain pure egolessness. It is to satisfy this unconscious inner desire of the soul that the world rotates around the axis of sex.
