What Am I Riddles

Question: I wasn't born a horse,
and I never fly.
Yet sometimes I still soar,
right into the sky.
I often contain breath,
and yet I never die.
Sometimes I am torn,
but I never sigh.

and go till I can go no higher.
Then, like many men, so great,
I sink into a low state.
What am I?
