Osho My Samasati

The Center is Silent, Observing

When sex is there and if you are not against it or for it, if you have no mind about it, then just by looking at the desire, your whole being will be involved in it. A single sex desire will become a flame.Your whole being will be concentrated in the flame, as if you have totally become sexual. It will not only be at the sex center, it will spread all over the body. Every fiber of your body will be trembling. The passion will have become a flame. Now, quit it. Don't fight with it, simply say, "I quit it."

What will happen? The moment you can simply say, "I quit," a separation happens. Your body - your passionate body, your body filled with sex desire - and you become two. Suddenly, in a moment, they are two poles apart. The body is writhing with passion and sex, and the center is silent, observing. No fight is there, just a separation - remember this.
