Editing Tanya (section)

== Kuntres Acharon ==
Like Igeres HaKodesh, Kuntres Acharon was first added to the Tanya in 1814. The "Kuntres" includes nine simanim:

The first five simanim of Kuntres Acharon are "deep pilpul and iyun on maamarei Zohar and writings of the Arizal that appear to contradict each other, and with his spirit of understanding he reconciles them":

* The first three reconcile apparent contradictions between perakim 39-41 in Tanya and the words of the Zohar
* The last two are explanations of Pri Eitz Chaim

The final four simanim are regular igros kodesh. We don't have an explanation for why these four igros were separated from the other igros kodesh (particularly since over the years many corrections were made both to the igros themselves and their order).
