I am currently reading The Book of Joy with the Dalai Lama and Desmond Tutu with Douglas Abrams. It isn't a book I ever would have chosen, but it was a gift to me at my retirement, so I felt like I should try to read it. So far, so good, although I think it could be condensed somewhat. It does not offend my atheist sensibilities, to my surprise.
Zoe Girl, this seems like something you might like. Catherine too, since I know you like the Dalai Lama. I think someone mentioned thisbook up-thread, but I cannot find the reference, so apologies if one of you already mentioned it.
