Siman 76

(17.) Pertaining to the New Aleph-Beis, under the letter Da'as, Torah §1, at the end: "And he also knows their unity — namely their beginning and their end [tachlis] — for in the beginning and the end they are in unity without distinction." Perhaps this was the intention of Rabbainu o.b.m. in the Torah that begins "Lechu chazu mif'alos Hashem" [Come, see the works of G-d] (Likutay Moharan, vol. 2, Torah 39) — for everything has a beginning and an end etc., see there well. And perhaps his intention was the aforementioned matter: that one must merit to know and to attain the aforementioned matter — that in the beginning and the end they are in unity without distinction. For I did not merit to understand this Torah well at the time I heard it from his holy mouth. And also when he saw the Torah in writing, he said that I had not captured his intent — and he said in these words: "I did not say it that way," and even "that was not even my intention." And perhaps his intention was the aforementioned matter, which I did not explain there in writing — and therefore he said that I did not capture his intent. And G-d knows secrets.
