groisnaches~ what I find very poignant is that you & your husband had already received a bracha from the Rebba, shlita, and yet:
“and on my way out, just before leaving the room, I asked if there’s anything I can take upon myself for special Hatzlacha with important things. ” … you asked for it, you got it.
as has been said before here on this thread: if you seek the advice of a Rebba, be prepared to receive it.
(I don’t mean to sound cold & insensitive.)
