Gitanjali 62

When I bring to you coloured toys, my child, I understand why there is such a play of colours on clouds, on water, and why flowers are painted in tints—when I give coloured toys to you, my child. 
   When I sing to make you dance I truly know why there is music in leaves, and why waves send their chorus of voices to the heart of the listening earth—when I sing to make you dance. 
   When I bring sweet things to your greedy hands I know why there is honey in the cup of the flower and why fruits are secretly filled with sweet juice—when I bring sweet things to your greedy hands. 
   When I kiss your face to make you smile, my darling, I surely understand what the pleasure is that streams from the sky in morning light, and what delight that is why the summer breeze brings to my body—when I kiss you to make you smile.
