Editing The Alter Rebbe (section)

== His Innovations and Enactments ==
The Alter Rebbe was a pioneer not only in Chassidus but also in halacha and custom. Besides the Shulchan Aruch he composed, the Alter Rebbe instituted several enactments and innovations:

* Sefer HaTanya - the way of serving Hashem
* Prayer text - a siddur suitable for every soul
* Polished knives - polishing shechita knives on both sides of the blade
* STaM script - a new form of letters combining Kabbalah and halacha
* Division of Shas - completion of the Talmud yearly by each Chabad community
* Mikvah enactment - halachic solution facilitating immersion in a spring
* Arev Kablan - selling chametz to a non-Jew before Pesach through a guarantor
* Tefillin knot - special method in tying head tefillin and arm tefillin
