"(The group began to make the sound. The Peulhs were still staring into the mirrors. I watched the actors grow hesitant, uncertain whether to continue. But the sound stretched and grew- and the Peulhs unexpectedly looked up from their mirrors for the first time. The sound took life, vibrating. The Peulhs discarded their mirrors and joined the sound. Oh, it seemed miraculous! It was as if the Peulh were pulling the sound from them. They pointed to the sky.

Just as the unimaginable sound reached its height, or seemed to, no one would venture any further. Somehow it was frightening. The two sides had met and come together in one sound. And yet it was as if they were stunned and frightened of the discovery. Ted Hughes has written of the sounds far beyond human words that open our deepest and innermost souls to sudden attention. Was this such a sound? For everyone making it, the Peulhs and the actors together, stopped suddenly and would go no further.

But now the Peulh offered an exchange and sang their songs. And they told Brook something very precious. He knew at last that he was on the right road in the search for a universal language. Perhaps we were only beginning to understand. But spirits speak there, in invisible worlds. (p128-129))........

He told me that if you watch any cat, it isn't just that his body is so relaxed and expressive. Its something more important than that. A cat actually thinks visibly. If you watch him jump on a shelf, the wish to jump and the action of jumping are one and the same thing. Theres' no division. A thought animates his whole body. Its in exactly the same way that all Brook's exercises try to train the actor. The actor is trained to become so organically related within himself, the thinks completely with his body. He becomes one sensitive responding whole, like the cat. 

An ultimate example of this state is revealed in a film of Picasso at work. in one lightning stroke you can see how the tip of Picasso's brush captures his entire imagination. His brushwork can actually be seen as his thought process. The same is true of the great orchestra conductor. After years and years of work, he thinks and transmits as one gesture. The whole of him is one. And it can be the same with the actor."
