OK I looked up the actual sicha – have you looked it up toi? There are sources right there.
So much for the Rebbe being his own source. But here I’ll translate for you, since we’ve come this far:
From acharon shel Pesach, 5710 (the Frierdiker Rebbe was nistalek then, and the Rebbe had farbrenged the whole year about keeping hiskashrus with the Frierdiker Rebbe, until he was forced to take on the nesius).
“Some ask, how can one even ask anything from a Rebbe, isn’t this the idea of a mimutza – intermediary between a person and Hashem?
Others ask this in connection to matters relating to yiras shomayim-
There is a meshulach who would accept pidyonos with regards to Gashmius matters, but not Ruchnius ones because he would say, even Hashem Himself doesn’t do this, as it says “Hakol bidei shomayim chutz miyiras shomayim.”
And the answer to this is:
When we say “Yisrael, Torah and Hashem are all one” (Zohar), we don’t only mean that “Yisrael connect to Torah which is connected to Hashem,” (Zohar chelek gimmel, 73a), but that they are actually one.
So too with the hiskashrus between chassidim and the Rebbe, it’s not like two separate entities which then unite, rather, they are actually one. And the Rebbe is not a mimutza hamafsik (which is avoda zara -ed), but rather a mimutza hamechaber. (More on this later as is concept in its own)
So automatically, by a chossid, he, the Rebbe and Hashem, are all one.
I haven’t seen this explicitly stated in Toras HaChassidus, but this is my hergesh, so automatically, whoever gets it, will feel it, and whoever doesn’t, I don’t want to argue with him, he can be as he is.
And so automatically, there is no place to ask about a mimutza, because this is Hashem’s essence as He has clothed Himself within a body.
This is like the quote of the Zohar, “The face of the Master, Hashem, is Rashbi”
(footnote : I have seen baalei Nigleh asking on this, and with a great shturem, hayitochen etc etc. But there is an explicit reference in nigle as well, and this is in the Yerushalmi bikurim chap 3, halacha 3: “and Hevaya in His Holy chamber, this refers to R’ Yitzchak the son of Rabbi Elazar in the beis midrash of Kisarin.)
Or as we also find that even a malach who is fulfilling Hashem’s shlichus is called by Hashem’s name at that time, (see Tanya iggros kodesh end of chap 25), or as Moshe rabbeinu said, “And I will give grass” (Ekev 11, 15. Also see likutei Torah vayikra 50, 1)”
Ok so that’s the full quote that toi is having a hard time understanding. If you actually saw it inside as posted, you’d have seen sources there, so the Rebbe didn’t make it up and it wasn’t about himself.
Now if you’d like to understand more about the difference between mimutza hamafsik vs mimutza hamechaber, or any other point that isn’t clear, I’ll be happy to clarify. Just make sure it’s phrased appropriately so that I can explain :).
