The Cohanan summarizes Yom Kippur
I was speaking to my dad a couple of days ago and he reminded me to buy Yahrzeit candles (traditionally candles that honor the dead that burn for 24 hours). One would be to honor my mom's passing (in Judaism this year it's two weeks after the actual date) and one for Yom Kippur, when Kaddish is said, the prayer for the dead.
The Jewish New Year seems welcoming and a cheerful occasion. Yom Kippur comes after and is deeper. One gives serious thought to things. I asked the Cohanan in a couple of sentences to sum up Yom Kippur. He said, "First, it is to ask forgiveness from God for things done wrong (sins) the previous year. He added. "it is often hard to know what we have done wrong." So true.
"Secondly, one prayers for blessings for health and well being in the coming year." If one goes to an orthodox synagogue one sees men and women hunched over their prayer books for 12 hours or so reciting prayers relating to these two thoughts. Personally, I'll fast that day and ponder these two items all day as life permits.
