a wind that takes my soul away

What am i doing here? Why, in fact, am i sitting here at all. i wonder what the purpose is. why i would be required as part of this mysterious divine scheme. for it seems to me that sometimes i am not required here; that people around me are capable of living out their existences without my influence. sometimes i feel as though i should just walk away, and that if i did, none would be concerned. they would all be concerned with themselves, and hardly notice that a wind had blown at all, a wind that takes my soul away on its gentle breath.
