Editing Tanya (section)

== Parts of the Tanya ==
The Sefer HaTanya is divided into five parts. The Frierdiker Rebbe compared the four parts of Shulchan Aruch to its four sections:

# Sefer Shel Beinonim - Contains guidance for maximizing the natural abilities and kochos of the nefesh, showing how a person can progress and elevate themselves in avodas Hashem until reaching the madreiga of beinom. Contains a hakdama and 53 perakim.
# Shaar HaYichud V'haEmunah (or Likkutei Amarim Part Two) - A secheldik explanation of the Baal Shem Tov's chiddush regarding achdus Hashem. Contains a hakdama called "Chinuch Katan" and 12 perakim. It was printed as an appendix to the first part.
# Igeres HaTeshuvah - Explains the essence of teshuvah according to Toras HaChassidus. Contains 12 perakim. In the first edition (Zolkva 1799) it wasn't divided into perakim, and in the second edition (Shklov 1806) the Alter Rebbe added the division into perakim.
# Igeres HaKodesh - A collection of 32 letters written by the Alter Rebbe "to guide am Hashem in the way they should go and the deeds they should do." Was added to Sefer HaTanya only after the Alter Rebbe's histalkus by his sons, his memale makom. First printed in Shklov in 1814. In writing this section, the Alter Rebbe wasn't as meticulous as in the first three parts of the Tanya.
# Kuntres Acharon - The Alter Rebbe's explanations on several sugyos discussed in the first part 'Likkutei Amarim', which weren't detailed there due to the focus on practical eitzos in avodas Hashem. Contains 9 simanim. First printed in Shklov 1814. Was added to Sefer HaTanya by his sons and memale makom after his histalkus. In writing this section too, the Alter Rebbe wasn't as meticulous as in the first three parts of the Tanya.
