Reply To: Kohanim not being able to go to exhibits with real dead people.

the baalei mussar say that hte reason that certain mitzvos are kept by the frei ie pesach yom kippur milah and a few others is either because the frum keep it stringently and that makes a hashpa’ah (not the ‘them seeing it and getting a hashpa’ah, rather a haspa’a m’lima’aleh) so the frei do to. or its the actual ntrinsic kedusha of these specific mitzvos that saves the frei from abandoning them and draws them to these mitzvos
