Chossid: “but even then it is told that the Rebbe didn’t sleep a whole sukkis because of the chshash”
I’m glad you wrote “it is told” because this is one of the stories that someone made up and became viral. What about the gemoro that someone who makes a shevuo that he won’t sleep for 3 consecutive days is lokeh miyad and can sleep, as it is a shevuas shov since it is impossible? Or will you say that your rebbe is different?
I remember the belief in lubavich even after gimmel Tammuz was that the rebbe never slept, and at best he dozed in a chair for a short period. Then the book written by someone who helped at the rebbe’s home came out in which he said clearly that he would put multiple negel vasser bowls near the rebbe’s bed because the rebbe would have to get up a few times in the middle of the night (due to his age).
