Hayom Yom 10 Cheshvan - The Alter Rebbe's exhilaration from Atzilus

דעֶר רֶבִּי (רַבֵּנוּ הַזָּקֵן) פלעֶגט זאָגעֶן אוֹיף אֲצִילוּת "אוֹיבּעֶן". מעֶן דעֶרצֵיילט אַז אִין כְּתָב פלעֶגט עֶר פוּן הִתְרַגְשׁוּת, מעֶר וִוי "אֲצִי" נִיט קעֶנעֶן אָנשׁרַייבּעֶן.The [Alter] Rebbe used to refer to the World of Atzilus (אצילות) as “above.” As is related, writing about this concept would bring him to such exhilaration that he could write no more than its first three letters — אצי.
