Parsing Power

This is from “The Last Aria” by Elizabeth A. Lerner:

I have great power over small things. I have small power over great things. I pray with thankfulness that I continue to notice these things, that I save what I can and mourn what I cannot. I pray also that I hear always the imperative song of the larger world, so impervious to my vision and efforts. I pray I will not tire of playing my own song out to the world, that I will not give up when it is not heeded, that help will come when I am tired and alone—and that it might be enough.
