Andrei Konchalovsky. (№ 327650)

You are interested in the amount of experience gained? Once a Zen teacher gathered his disciples to share with them the amount of experience gained. He opened his mouth, and at this time on the branch sat a little bird and sang. The master looked at the bird and heard, and they all sat and listened. The bird finished and flew away. Said the master: here endeth the lesson. That was the amount of experience gained. More than the bird that sang, can't tell.
