After a while, if you're committed, you start to believe in the things in which you're praying. It's just cognitive dissonance. You can't live a completely religious life and not start to have it sink in.

I'm still agnostic. But in the words of Elton Richards, I'm now a reverant agnostic. Which isn't an oxymoron, I swear. I now believe that whether or not there's a God, there is such a thing as sacredness. Life is sacred. The Sabbath can be a sacred day. Prayer can be a sacred ritual. There is something transcendent, beyond the everyday. It's possible that humans created this sacredness ourselves, but that doesn't take away from its power or importance.

When I went to Israel, it was a little disorienting, because there are so many people who look crazy and were dressed like me. There, I was just one of the apocalyptic crowd.

I got a sense of the amazingness of ordinary life, and I became aware of the marvel that we're around to begin with. I visited a lot of extreme communities, like the Amish, Hasidic Jews, and serpent-handlers. And I was proud, because I think I'm the first person to ever out-Bible-talk a Jehovah's Witness. After four hours, he said, "Okay, I have to go."

The best we can do, to paraphrase Pollan, is to eat whole foods, mostly plants, and not too much.

Think of negative speech as verbal pollution. And that's what I've been doing: visualizing insults and gossip as a dark cloud, maybe one with some sulfur dioxide. Once you've belched it out, you can't take it back. As grandma said, if you don't have anything nice to say, don't say anything at all. The interesting this is, the less often I vocalize my negative thoughts, the fewer negative thoughts I cook up in the first place.

This is what the Sabbath should feel like. A pause. Not just a minor pause, but a major pause. Not just lowering the volume, but a muting. As the famous rabbi Abraham Joshua Heschel put it, the Sabbath is a sanctuary in time.
