What is the source of this story found in many non-traditional machzorim?
Late one Yom Kippur afternoon in Berdichev, Rabbi Levi Yitzhaq went up and argued with God that his people deserved to be saved. He was about to sway Him! Then, out of the corner of his eye, he glanced down and noticed that Hayyim, the laundry man, had fainted from hunger. He started to rush back down to conclude the service so that Hayyim could eat. The angels went after him, saying, "Reb Yitzhaq, what about saving the world?" He answered, "Where is it written that saving the world must come at the price of the life of Hayyim, the laundry man?" And he rushed back to conclude the service. And he heard a chorus of angels calling after him: "Levi Yitzhaq, you ARE saving the world!"
Very inspirational, but weak in teaching Judaism:
-If you faint from hunger, eat. Yom Kippur or not. Your life comes first. (Pikuach nefesh.)
-Yom Kippur ends at sundown, 25 hours after it begins, whether or not the prayers have been completed. You can rush and daven Neilah at noon, but that won't make Yom Kippur end any sooner.
So does anyone know its source?
