I'm asking this to the chabadnikim here.
When I see seforim written after the Rebbe passed away and it refers to him as Shlita and not ZT"L, does it mean it was written by a nut, or is it b/c he is still 'alive' through his teachings?
And if it's the latter, do they do this with all their rabonnim?
(My bad if this was asked before/)
