Every spring I hear the thrush singing in the glowing woods...

Every spring I hear the thrush singing in the glowing woods he is only passing through. His voice is deep, then he lifts it until it seems to fall from the sky. I am thrilled. I am grateful. Then, by the end of morning, he's gone, nothing but silence out of the tree where he rested for a night. And this I find acceptable. Not enough is a poor life. But too much is, well, too much. Imagine Verdi or Mahler every day, all day. It would exhaust anyone.
