Yizkor in Hebrew means “to remember.” Memory is transcendence.
We are creatures blessed with memory. We can transcend not only time, but space, and even the boundaries of the physical world.
With the memory of your parents, you break through the barrier between the physical world in which you dwell and the spiritual one to which they have ascended. As you connect to them through your memory of them here in this world, so do they connect to you by remembering you from their world.
In the prayer, we pledge to give charity in their memory. When we give charity on their behalf, their souls ascend yet higher with that merit. And they then provide to you guidance and blessing, much more than they were able to from within this world.
See Yizkor: Recalling the Dead, from the Jewish Death and Mourning minisite.
When we should kindle the candle light for Yizkor ? From 4 holidays ,which I don't know should lit the candle after or before lit the holiday candle ? Please make me clear as I know one thing we should recite Yizkor prayer after we read and pray for holiday ,is it correct ? Thank you
A Yizkor/Yahrtzeit candle is lit before Yom Kippur starts and see this link for a list of dates when Yizkor is said and the candle is lit.
Light the Yahrtzeit candle first, then light the Yom Kippur holiday candles and say the blessings on those.
