“The reason why R’ Chaim Kanievsky is so makpid on “new names” is because the Arizal writes that from the zman of Bais Sheini, there is no such thing as a “new nishama”, rather we are all gilgulim. And since the name is a connection to the nishama, we should stick to old names.”
Thank you for explaining this shita of R’ Chaim. It’s nice to finally have some hard facts here.
