[Avodah] yuhara

[Joel Rich]

If something isn't "mkubal" (accepted practice), even though it has
significant mkorot, (sources) when does it become yuhara (arrogance) to do
it? Four recent discussions I've had: saying al naharot bavel before
birchat hamazon during the week, saying kriat shema with trop, putting on
tallit and tfilin outside shul and saying hareini kaparat mishkavo for a
parent in the first year after their death. Any thoughts?
