CS you wrote: “I have experienced the Rebbe’s greatness myself on many levels.”
I find this very significant.
If I recall correctly you worte that you were born a few months before the lubavitcher rebbe did/did-not (strike out whichever is inapplicable) pass away. So you clearly never saw him, spoke to him face to face etc..
How then can you say that you have experienced his “greatness myself on many levels”? Don’t you believe tht Hashem is running the world? Maybe, just maybe, it was Hashem you experienced and not the rebbe at all.
If c”v someone beseeched oisoi ho’ish to heal him, ahd the person was then healed, we would all laugh at the idea it was o-h who healed him and we would all agree that it was Hashem who did so.
So please tell us how you know it was the rebbe you experienced.
