“One is required to light a yahrzeit candle (memorial candle) before a Yom Tov when Yizkor is said.”

Our sages say: “One cannot sit down to eat breakfast a day after saying Yizkor before making a contribution towards their Yizkor pledges.”

The Midrash says: “During Yizkor, the departed soul gets immersed in holy waters and gently washed. Its status becomes pure as a newborn, and benefits from sitting amongst worthy tzaddikim in Gan Eden.”
