Suffering occurs when we want other people to love us in the way we imagine we want to be loved, and not in the way that love should manifest itself--free and untrammeled, guiding us with its force and driving us on.
I once thought that if I could ask God one question, I would ask how the universe began, because once I knew that, all the rest is simply equations. But as I got older I became less concerned with how the universe began. Rather, I would want to know why he started the universe. For once I knew that answer, then I would know the purpose of my own life.
