CS,
” (I watched a video of his descendent testifying to the above. That the Gra saw the Alter Rebbe through the keyhole of his door in Vilna, and realized there was so much kedusha there that he would have become a chossid, ”
Do you really believe everything someone says on a video – only because he claims to be a descendant?
I have read plenty of material on that issue, good and bad– sorry, but this is utterly nonsense. The Gra never bothered seeing the Alter Rebbe, nor did he have any issues with emotions. Meaning, if he felt there is real kedusha,he would have no issue facing it.
You are not speaking about some nowaday Rosh Yeshiva!
The gra when he finished writing his pirush on Shir hashrim, he stated to his talmid: he has completed all torah, niglah and nistar to the level of keSinusei m’Sinai, he has only one question in nistar, which he would travel to the other end of the world to find an answer…Do you really think he couldn’t face the truth?!
Anyways, i’m sure in Chabad they think the Gra was no comparison to the Alter Rebbe, and had they met he would surely convinced him…
