Eye am.

I am when I give.
I am when I teach.
I am when I cover my eye, bring peace.
I am when I open my eye, evils defeat.
I am when I plant a tree, but sit in the sun.
I am when I give once, twice, take none.
Other than that
I am not.
I am none.
I am electrons in motion.
I am when in devotion.
Today I am caught.
Later today I am not.
I am always in change.
I am in and out the race.
I am everything when I am done.
I am most when I am none.
