Answer:
As a stone inside a tree, I’ll help your words outlive thee. But if you push me as I stand, the more I move the less I am.
What goes through a door but never goes in and never comes out?
I eat I live.I breathe I live. I drink I die.
Without a bridle or a saddle across a thing I ride a-straddle. And those I ride by help of me though almost blind are made to see.
A hundred arms, a thousand fingers, but I have no eyes to see where I linger. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
