A haiku by Basho:
I CLAP MY HANDS AND WITH THE ECHOES IT BEGINS THE DAWN - THE SUMMER MOON.
Basho is one of the greatest poets of the world, but he has written only haikus - very symbolic but very miraculous, very simple but very mysterious. They are all to be understood through visualization, because Zen does not believe in words. Visualize and perhaps you may have some understanding. "I clap my hands and with the echoes" - in the mountains - "it begins the dawn - the summer moon."
The summer moon is still hanging and the sun is going to rise. And I have clapped my hands, and the echoes are still resounding in the mountains. It is just a painting in words. A haiku has to be understood - a painting in words, not only a poetry in words - and it has to be visualized. Just visualize yourself surrounded by mountains. And you...(OSHO CLAPS HIS HANDS.)... clap your hands. The mountains go on echoing and the summer moon is still there and the dawn has come.
The sun will be arising soon.
Why should he write these small haikus? He used to live by the side of a lake surrounded by mountains, meditating in utter silence. Once in a while he would open his eyes and whatever he would see, he would note down. These haikus are not out of the mind. These haikus are reflections in a mirror, in a no-mind. In a silent heart the summer moon, the dawn very close and he claps his hands, and all the mountains resound with echoes.
A meditator, according to Basho, will go on searching deep within himself, but that does not mean that he should lose contact with the outside world. Once in a while he should open his eyes. With all his emptiness he should mirror the outside world. Those reflections are collected in these haikus.
They don't mean anything, they simply depict a picture.
