I knew my soul was sick and that I needed spiritual advice, and I knew also that this advice shouldn't be terribly sophisticated. So I went to see the pastor of my son's preschool....
I said that I was all over the place, up and down, scattered, high, withdrawing, lost, and in the midst of it all trying to find some elusive sense of serenity. "The world can't give that serenity," he said. "The world can't give us peace. We can only find it in our hearts."
"I hate that," I said.
"I know. But the good news is that by the same token, the world can't take it away."
