A few days ago I heard an interview with this man, on NPR or somesuch, and he was such a nice guy, so positive and cheerful. His father told him, when he was a kid, to "be such a man, live such a life, so that if everyone lived like you this would be God's paradise" (more or less, from my faulty memory).
That seems to be a perfect statement of how to live. Of course, we'd soon get into interpretations of "God's Paradise" and trouble with fundamentalism, persecution of non-believers (If they JUST LIVED LIKE I DO life would be perfect; we must force them to do so!) and so on.
Because people are, in the bulk, idiots.
Still, a good restatement of the golden rule.
