"I have heard about an artist:

"He had gone to the forest. It was a beautiful day; the birds were singing songs, and in the background the noise of the insects was like a continuous melody. And the earth was wet, and the freshness of the air, and the smell of the wet earth…he was infinitely enchanted. And the trees and the greenery, and then the sudden appearance of the sun out of the clouds, and then a cuckoo started calling from a distant valley, and then a rainbow…and he was so happy, he was in such a delirium of joy, that he wanted to make this moment eternal. He wanted to paint it or carve it on wood or do something, write a poem or sing a song or compose music. But nothing was available there, and he did not want to miss the moment and the beatitude of it, so he started carving on wood. He had a knife so he started carving. But how do you carve the constant melody of the insects? How do you carve the singing of the birds? And how do you carve the sudden burst of the sun? And how do you carve a bird on the wing balancing itself in the sky? And how do you carve the smell of the wet earth? And how do you carve the sharpness, the freshness, of the air? Soon he was disappointed. He tried hard, but there was no way to carve it, and whatsoever he carved looked silly.

"That's what has been happening to all the definitions of religion. Each definition, once you have carved it, looks silly. First, because religion is vast. Second, it is an inner experience, it is a taste on the tongue or a smell in your nostrils or a feeling in your heart. By its very nature it cannot be reduced to words, to doctrines and creeds. It is a simple experience, very simple, but the very simplicity creates the problem. If it were a complex experience there would be a possibility of defining it. Complex things are easy to define, simple things are impossible to define. How do you define the color yellow? You can say yellow is yellow – what else is there to say? But to say yellow is yellow is not a definition, it is a tautology; you have not said a single thing more that was not already said in the word yellow itself."
