Gitanjali: 37

I thought that my voyage had come to its end at the last limit of
my power,—that the path before me was closed, that provisions
were exhausted and the time come to take shelter in a silent
obscurity.
But I find that thy will knows no end in me. And when old words
die out on the tongue, new melodies break forth from the heart; and
where the old tracks are lost, new country is revealed with its
wonders.
