Rabindranath Tagore was a Bengali poet, artist, and spiritual philosopher who won the Nobel Prize in Literature in 1913 for his seminal work The Gitanjali, which explores devotion, service, loss, and renewal. 

“The song that I came to sing remains unsung to this day.
I have spent my days in stringing and in unstringing my instrument.
The time has not come true, the words have not been rightly set; only there is the agony of    wishing in my heart.
The blossom has not opened, only the wind is sighing by.
I have not seen his face, nor have I listened to his voice; only I have heard his gentle footsteps from the road before my house.”
Rabindranath Tagore
