Question
Has the Rebbe ever addressed or provided guidance regarding an avel (mourner) completing the entire set of Mishnayos—the Shisha Sidrei Mishnah—during the year of mourning? If so, within what timeframe is this directive to be fulfilled?
Answer
Indeed, the Rebbe encouraged individuals to adopt the practice publicized by the Rebbe Rashab, specifically for mourners, to complete the entire Shisha Sidrei Mishnah by the conclusion of the eleven months of Kaddish recitation. At the very least, the Rebbe recommended studying the beginning and end of each tractate, a custom similarly observed in the completion of Tikkun Leil Shavuos.
