Episode notes
The epistle that follows, beginning “The letters that are revealed,” is one of the epistles that was appended to the edition of the Tanya published in Vilna in the year 5660 (1900), these additions being noted by R. Asher of Nikolayev in his introductory declaration there.53
This relevance of this epistle to the previous one may be found in the following parallel: The previous epistle explains how only the netzach-hod-yesod-malchut (i.e., the lower sefirot) of the Emanator extend to the recipient. The conclusion of the present epistle likewise explains54 that only the hindmost aspect and externality of the netzach-hod-yesod of the higher realm enter the lower one.
