Rabindranath Tagore 
Gitanjali 
Song Offerings

These lyrics— which are in the original, my Indians tell me, full of subtlety of rhythm, of untranslatable delicacies of colour, of metrical invention—display in their thought a world I have dreamed of all my live long. The work of a supreme culture, they yet appear as much the growth of the common soil as the grass and the rushes. A tradition, where poetry and religion are the same thing, has passed through the centuries, gathering from learned and unlearned metaphor and emotion, and carried back again to the multitude the thought of the scholar and of the noble.
