Yom Kippur

Maybe all of you already know a lot about this holiday, its origins and traditions, but I was interested in finding more about Yom Kippur, the most sacred of the Jewish holidays, the "Sabbath of Sabbaths."
I'll just mention the five prohibitions of Yom Kippur:

1. eating and drinking
2. anointing with perfumes or lotions
3. marital relations
4. washing
5. wearing leather shoes

I guess it'll be interesting to have it in mind each time it's mentioned in the book. I found a very interesting site if you want to learn more about it:
