Our study should include a teaching from each of the leaders of Chassidus: The Baal Shem Tov, the Maggid of Mezritch and the Rebbeim of Chabad.
Breadth and Depth
We should study (a) the teachings of each Chabad Rebbe on a range of topics; as well as (b) the various teachings of each Rebbe on a single subject.
Both endeavors have their own unique advantage: Studying the works of a single Rebbe allows for a deeper perspective, while studying a single topic from each of the Rebbeim highlights their respective innovations and provides a broader perspective.
More Each Day
Ideally, we should study more and more each day in Kislev, adding in both quantity and in quality – and continuing even after Kislev has passed.
Two approaches
The study of separate topics from each of the Chabad Rebbeim lends itself to more in-depth analysis than the study of all of the Rebbeims’ teachings on a single topic. On the other hand, by studying what all of the Rebbeim have taught on a single subject, it is possible to appreciate and discern the novel points that each Rebbe adds. (Parshas Vayeitzei 5749; Hisvaaduyos, p. 404, fn. 94)
Climax or catch up
Those who already began this study (of all the Rebbeim’s teachings) from the beginning of Kislev should certainly continue to do so; they should further increase their study in keeping with the precept to “constantly ascend in matters of holiness.” Those, however, who have not yet begun to do so – for whatever reason – should now make use of these propitious days, the ninth and tenth of Kislev, to made good their lack in the appropriate manner. (Ninth of Kislev 5749; Hisvaaduyos, p. 395) [See also Parshas Vayeitzei 5749 (Hisvaaduyos, p. 405).]
Festival of spiritual oil
It has been pointed out that the festival of Chanukah (the miracle of which symbolizes the “oil” – or inner teachings – of Torah) begins at the end of Kislev and then continues into the month of Teves. (Parshas Toldos 5749; Hisvaaduyos, p. 384, fn. 90).
