Kislev 19 is also the anniversary day of the first publication of Tanya (see article #2 to sample a chapter), an important primer for Kabbalah and Chasidut, as well as the celebration of the liberation of its author from prison a few years after on the same date (last article).
Articles 4-6 offer deep Kabbalistic insights into the weekly reading from the Zohar, the Alsheich and the Lubavitcher Rebbe, respectively.
