[2] Rabbi Schneerson's primary vehicle for conveying his teachings were the farbrengens held on Shabbat, the festivals, and special occasions in the Chabad Lubavitch calendar, at which he would speak for many hours.

Of the many of thousands of talks that Schneerson delivered, those that were the most basic to his weltanschauung and message were compiled in the Likkutei Sichot, which originally appeared in weekly pamphlets.

He reviewed and extensively edited each of these transcriptions before it went to press, making the Likkutei Sichot the authoritative medium with which to disseminate his teachings.

The edited Sichos represent much of Schneerson's central teachings, and unique spiritual voice for the generation, with other major works being the deeper, mystical Maamarim (Hasidic discourses), unedited talks, personal correspondence etc.

In 1964 the Lubavitcher Rebbe began his delivery of some 800 public talks over a period of over 25 years on the subject of Rashi’s commentary to the Torah.

The medieval French Rabbi Rashi is among the most important traditional Jewish commentators on the books of the Tanakh, and the many volumes of Talmud.

In the Rashi Sichos, Schneerson brings a new approach that initially cites all previous sub-commentaries from earlier authorities, and then proceeds to explain why each of them falls short.

He elucidates a deceptively simple explanation of Rashi that he often culminates by additionally relating his conclusions to their spiritual, mystical parallels and practical outcomes.

Each lecture of the Rebbe built on the previous one, gradually assembling a picture of Rashi’s commentary as an extremely organized, unified system of Torah exegesis.

Many who were present at these lectures at their inception in the late sixties and early seventies, recall how the “Rashi talk” was literally the highlight of the entire Sabbath afternoon gathering.

It can be said that in all of Schneerson's many-dimensional scholarship, he captures the simple essence of Hasidic mysticism, and unites it with the Revealed aspects of Judaism, always seeking to bring ideas into greatest tangibility, and above all practical outcomes ("The main thing is the deed").
