I'm not Hindu, but the religion is entertwined enough in my home-life that I feel bad missing the major holidays, when my brother and sister are close enough to come home for them. (Diwali is a celebration of the equivalent of the eternal flame or something like that... its on par in importance with Christmas).
Religion is one of those things I should sit and think through one day. I've had Christian leanings, but I don't know for sure if I feel that way or I'm just a lemming.
It also doesn't help that I'm missing it by one measly day. Oh well.. lots of post-Diwali food waits for me at home :-)
