Answer:
What is it that makes tears without sorrow and takes its journey to heaven?
I cost no money to use, or conscious effort to take part of. And as far as you can see, there is nothing to me. But without me, you are dead.
I have a face, yet no senses. But I don't really care, because time is of the essence.
What flies without wings? What passes all things? What mends all sorrow? What brings the morrow?
They can be harbored, but few hold water. You can nurse them, but only by holding them against someone else. You can carry them, but not with your arms. You can bury them, but not in the earth.
I can only be played on a windy day
