Humanity can be divided in two types: the sleeping ones and the awakened ones — and, of course, a small part in between.
Happiness will depend on where you are in your consciousness. If you are asleep, then pleasure is happiness. Pleasure means sensation, trying to achieve something through the body which is not possible to achieve through the body, forcing the body to achieve something it is not capable of. People are trying, in every possible way, to achieve happiness through the body.
The body can give you only momentary pleasures, and each pleasure is balanced by pain in the same amount, in the same degree. Each pleasure is followed by its opposite because body exists in the world of duality, just as the day is followed by night and death is followed by life and life is followed by death. It is a vicious circle. Your pleasure will be followed by pain, your pain will be followed by pleasure.
But you will never be at ease. When you will be in a state of pleasure you will be afraid that you are going to lose it, and that fear will poison it. And when you will be lost in pain, of course, you will be in suffering, and you will try every possible effort to get out of it — just to fall again back into it.
Buddha calls this the wheel of birth and death. We go on moving in this wheel, clinging to the wheel… and the wheel moves on. Sometimes pleasure comes up and sometimes pain comes up, but we are crushed between these two rocks.
But the sleepy person knows nothing else. He knows only a few sensations of the body — food, sex. This is his world; he goes on moving between these two. These are the two ends of his body: food and sex. If he represses sex he becomes addicted to food: if he represses food he becomes addicted to sex. Energy goes on moving like a pendulum.
And whatsoever you call pleasure is, at the most, just a relief of a tense state. Sexual energy gathers, accumulates; you become tense and heavy and you want to release it.
The man who is asleep, his sexuality is nothing but a relief, like a good sneeze. It gives you nothing but a certain relief. A tension was there, now it is no more there; but it will accumulate again. Food gives you only a little taste on the tongue; it is not much to live for. But many people are living only to eat; there are very few people who eat to live.
