Answer:
Voiceless it cries, Wingless flutters, Toothless bites, Mouthless mutters. What is it?
You heart it speak, for it has a hard tongue. But it cannot breathe, for it has not a lung.
Many have heard it, but nobody has ever seen it. It will not speak until spoken to. What is it?
It floats over the land, It cuts the tallest mountain, Its voice is like a fountain, Its body like a snake, Will flow into a lake.
When I'm born I fly. When I'm alive I lay. When I'm dead I run.
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
