"You see, at the center of all religions is the idea of Karma.
You know, what you put out comes back to you: an eye for an eye, a
tooth for a tooth, or in physics—in physical laws—every action is met
by an equal or an opposite one. It's clear to me that Karma is at the
very heart of the universe. I'm absolutely sure of it. And yet, along
comes this idea called Grace to upend all that as you reap, so you will
sow stuff. Grace defies reason and logic. Love interrupts, if you
like, the consequences of your actions, which in my case is very good
news indeed, because I've done a lot of stupid stuff."
