Gts Numen The Day After Yom Kippur

The day after Yom Kippur is called G-t's numen, "Hashem's name." (נאמען ס'ט-ג). What is the reason for this title?

1. The Baal Shem Tov zy'a explains that for ten days, we've been saying הקדוש המלך, and now we go back to saying הקדוש ל"הא in Shemonah Esrei. Therefore, this day is called G-t's numen, "Hashem's name."
2. Rebbe Yissachar Dov of Belz zt’l teaches: On Yom Kippur, the nation heard the kohen gadol say the Shem Hameforash (Hashem's name ה"הוי, pronounced as it is written). The Yerushalmi (Yoma 3:7) teaches that the way to pronounce and read Hashem's name must remain a secret, revealed only to a select few (see Kiddushin 71). Miraculously, immediately after Yom Kippur, the people forgot how to pronounce the name so that it would remain a secret. The morning after Yom Kippur, they were asking one another, "Do you remember how the kohen gadol pronounced Hashem's name?" Everyone was trying to remember, but they all forgot. Since everyone was speaking about G-t's numen, the day after Yom Kippur is called G-t's numen.
3. Rebbe Dovid of Lelov zy'a heard a melamed tell a young child, "When you see two consecutive yuds in the Chumash, that is Hashem's name." Once, the melamed reached the end of a פסוק (which is called פסוק סוף), and it appeared like this “: The student asked, "There are two yuds here; why don't you read it as Hashem's name?" The melamed replied, "When two yuds are next to each other, it is Hashem's name. But when one yud is higher than the other, it's a פסוק סוף, a separator between one pasuk and the next." Rebbe Dovid of Lelov said he learned from this that when two Yidden (two yuds) feel equal, with no one feeling superior to the other, Hashem is there. But when one feels higher than the other, it's a separator, and Hashem doesn't reside there. Rebbe Moshe Mordechai of Lelov zt'l repeated this story and added: After Yom Kippur, everyone is cleansed from sin, so all Yidden are on the same level. That's two yuds side by side, and Hashem's name is there. Therefore, the day after Yom Kippur is called G-t's numen because everyone feels equal, and Hashem's name is there.
