Ignorance
I realized today that I didn't know anything about what Sikhs believe.
I've just started reading about them, but it seems to be an amalgam of (or perhaps reaction to is a better term) Hinduism and Islam.
I vaguely recalled buying a book on the Sikhs a while back (I bought it after seeing an exhibit at the National Museum of Natural History; while I couldn't find it, I did find a half dozen books on Buddhism I've acquired over the years, none of which I've actually read.
That's too bad, and something I'll have to rectify. I am definitely not a Buddhist, but I often find that many (though definitely not all, including some important ones) of my attitudes are quite consistent with the tenets of Buddhism.

I recommend "Awakening the Buddha Within" by Lama Surya Das. It was one of the first books I read, and it's really attuned to the western way of life and easy to read.
Oh, and thanks for the link to the Sikh page. I was only vaguely aware that I liked their philosophy, but was never really clear why (aside from the Sikh graduate student I had a tiny crush on many years ago.)
Thanks for the recommendation--I don't have it, but I'll see if I can get it from Amazon,
