I would advise anyone who is at the start of a rest ritual like the Sabbath, to take it slowly and grow incrementally into it. Recognize that it will be hard at first. It's a discipline but then it is a true and deep joy.

I took to religion at about age 12; it was very hard for me to be Sabbath observant as a kid in a home which was not Sabbath observant. I think my parents thought the whole Jewish thing was a phase.

I don't read or write SF for cutting edge ideas; I read and write it for the storytelling, and every story is new. So have I brought anything new to it? Only in so far as no-one before has written about the characters I've invented in their particular situation.

I have a principle I often invoke in class: comfortable people don't grow. Good teachers need to engage in the paradox of making students feel comfortable and uncomfortable in equal measure.

For me, study is a divine and daily imperative, and I study a page of Talmud daily so that I am not only teaching. My teaching is constantly being fed by my learning.

In order to survive, the human race must defend itself.

I love going to synagogue on Friday night and being swept in the melodies. Everyone seems more friendly and unburdened by the week and ready to be taken elsewhere.
