You move into the world almost only through the eyes; they say eighty percent. Those who have been working with eyes, the psychologists, they say that eighty percent of contact with the world is through the eyes. Eighty percent of your life moves out through the eyes.
That's why whenever you see a blind man, you feel pity. You never feel so much pity and sympathy when you see a deaf man, but when you see a blind man, suddenly you feel sympathy and compassion. Why? -- because he is eighty percent non-alive. A deaf man is not so non-alive. Even if your feet are cut and your hands are cut, you will not be so unalive, but a blind man is eighty percent closed; he lives only twenty percent.
Through your eyes eighty percent of your energy moves out. You are moving into the world through the eyes. So when you get tired, the first thing is the eyes. Later on, other parts of the body will be affected; the eyes will be the first to be drained of energy. If you can refresh your eyes, you can refresh your whole body, because they are eighty percent of your energy. If you can revitalize your eyes, you have revitalized yourself.
In a natural surrounding you never feel as tired as you feel in an unnatural city, because in a natural surrounding your eyes are continuously fed. The greenery, the fresh atmosphere -- everything relaxes your eyes and feeds them. In a modern city everything exploits your eyes and nothing feeds them. So move to a remote village, or to a hilltop where nothing artificial is in the milieu, where everything is natural, and you will see a different type of eyes. The twinkling, the quality, will be different -- fresh, animal-like, penetrating, alive, dancing.
In a modern city, eyes are dead; just living on the minimum. They don't know what festivity is. They don't know what freshness is. The eyes are unaware of any life flowing through them; they are just being exploited. Eighty percent of your energy moves from your eyes, so you have to be perfectly aware, and you have to learn an art about this movement, this energy, and the possibility of the eyes.
In India we have been calling blind men PRAJNA-CHAKSHU -- wisdom-eye -- for a particular reason, because every misfortune can be transformed into a great opportunity. Eighty percent of the energy moves through the eyes, and when a person is blind, he is eighty percent not alive; with the world eighty percent of his contact is lost.
He is very poor as far as the world without is concerned, but if he can use this opportunity -- this opportunity of being blind -- then he can use this eighty percent of his energy for his inner world; this eighty percent that you cannot use ordinarily unless you know the art. So eighty percent of his energy is with him, it is a reservoir, and the energy that normally moves out can move within. If he knows how to allow it to move within, he will become a wisdom-eye.
A blind man is not a PRAJNA-CHAKSHU, a wisdom-eye, just by being blind, but he can be. He doesn't have ordinary eyes, but he can get the eyes of wisdom. The possibility is there. We named him PRAJNA-CHAKSHU just to make him aware that he should not be sorry that he doesn't have eyes. He can create an inner eye, and eighty percent of energy is with him which is not with those who have eyes. He can move it. He can use it.
Even if the blind man is not aware, he becomes more silent than you are. He becomes more relaxed. Look at a blind man. He is more silent. His face is more relaxed. He seems to be at ease with himself; no discontent. This will not be the case with a deaf man. He will be more restless than you, and he will become cunning. But a blind man is never cunning, never restless, never calculative; basically trusting, in a deep faith with existence.
Why does this happen? -- because the eighty percent of energy, even if he doesn't know anything about it, is moving within. It becomes a constant fall, just like a waterfall. Even unaware, it goes on falling on his heart. The same energy that moves out, goes on falling on his heart -- that changes the quality of his being. In ancient India the blind man was very much respected -- very much respected. In deep respect we called him PRAJNA-CHAKSHU, wisdom-eye.
The same you can do with your eyes, and this technique is for that: to help your energy which moves out to fall back upon yourself, upon your own heart center. If it falls on the heart, you become as light as possible. You feel as if the whole body has become a feather; as if gravitation has absolutely no effect on it. And immediately you are connected with the deepest source of your being, which revitalizes you.
