You may not have observed this because it is impossible before you go into deep meditation; you cannot observe the fact that the whole universe breathes. And just as you expand and shrink the whole existence shrinks and expands. Just as you inhale and the chest fills, and then you exhale and the air goes out and the chest shrinks, the same rhythm exists in existence. The whole existence breathes, expands, inhales, exhales -- and if you can find the rhythm of existence and become one with the rhythm, you have attained.

The whole art of ecstasy, meditation, samadhi, is: How to become one with the rhythm of the universe. When it exhales, you exhale. When it inhales, you inhale. You live in it, are not separate, are one with it. Difficult, because the universe is vast. A master is the whole universe in miniature. If you can learn how to inhale with the master and how to exhale with the master, if you can learn simply that, you will learn all.
