In the Chinese Taoist tradition, they have a method known as "Tai-Chi". It is a method of centering, a method of witnessing. They say do whatsoever, but remain conscious of the center at the navel. Walking, be conscious of the center at the navel. Eating, be conscious of the center at the navel. Fighting, be conscious of the center at the navel. Do whatsoever you are doing, but remain conscious of one thing: that you are centered in the navel. Again, if you are conscious of the navel, you cannot think. The moment you begin to think, you will not be conscious of the navel.
This is a body technique. Buddha uses breathing, breath; Taoists use hara. They call the center at the navel hara. That's why Japanese suicide is known as hara-kiri. It means committing suicide remaining centered in the hara so it is not suicide, it is not just suicide. They call it hara-kiri only if a person commits suicide remaining continuously aware of the center at the hara. Then it is not suicide at all -- he is doing it so consciously. You cannot commit suicide so consciously. With you, suicide is committed only when you are so much disturbed that you have become absolutely unconscious.
Whether you use the hara or you use breathing, you must remain conscious. Krishnamurti says, "Remain conscious of your thought process." Whether it is the process of breathing or the palpitation of the hara or the thought process, it makes no difference. The basic thing remains the same.
Remain conscious of your thought process. A thought arises: know that it has arisen. A thought is there: know that the thought is there. When the thought moves and goes out of existence, then know, witness that it has disappeared. Whenever a thought goes and another thought comes, there is a gap in between. Be conscious of the gap. Remain conscious of the thought process -- a thought moving, a gap, again a thought. Be conscious!
