Tamuz 28

Each of the Rebbe'im had maamarim designated especially for the purpose of purifying the atmosphere. Every two or three years they would review and recite them publicly. One of (these special) maamarim of the Alter Rebbe was Hechaltzu printed in Likutei Torah (without the glosses). One of the Mitteler Rebbe's was Yafa sha'a achat; (its subject was the first ten chapters of the maamar Hinei kol echad v'echad in Derech Hachayim). One of the Tzemach Tzedek's was Ma tovu, printed in Likutei Torah. One of my grandfather's (the Rebbe Maharash) was Mi chamocha. One of my father's was V'yadata hayom, Moscow - 5657.
