However, I found a good website with Tagore's Chinese and English versions of Birds and other works, but there is no English version.

"Water has no brilliance and swings; There is no fire in the stone, but light comes from collision. "

The plain of water ripples; The stone rubs the dumb fire, but it collides with the light of life.
