The sound of the rain needs no translation.
That's a waste of time. If you really understand Zen... you can use any book. You could use the Bible. You could use Alice in Wonderland. You could use the dictionary, because... the sound of the rain needs no translation.
The sound of the rain needs no translation. In music one doesn't make the end of the composition the point of the composition... Same way in dancing, you don't aim at one particular spot in the room... The whole point of dancing is the dance.
