The power of saying Na Nach Nachma Nachman MayUman

 HH unfortunately I can't find the post about this, in short some guy at the holy tzion many years ago told me that he or his wife were feeling very dejected after being ridiculed for being Nanach, and they dozed off and Rabbainu's mother came in their dream and told them what have you to be dejected about, every time you say Na Nach Nachma Nachman MayUman 200 people have a thought of repentance. So right away I told him that there is evidence to the truth of the dream, because the Hebrew word for 200 - מאתים = Na Nach Nachma Nachman MayUman. Shortly thereafter friends got involved in doing hafatza to Pakistan and Afghanistan, and they said there were potentially tens and tens of millions of lost Jews there, so we understood we would need to be singing a lot of Na Nach Nachna Nachman MayUman.
