His Torah

It is said that when one of the Rebbe’s talmidim collected his teachings and wrote them down, he then showed them to the tzaddik. The volume was as large a tractate of Talmud, and the Rebbe reviewed them all. He only allowed to be printed those divrei Torah which he had no recollection of having said, because those, he explained, were true Torah, where the Shechina (Divine Presence) had spoken through his mouth. (Otzar Yisrael 4)
