Rav Sholom Shachne Zohn And The Chofetz Chaim

Rav Sholom Shachne Zohn came all the way from America to study Torah in Yeshivas Mir in Poland . The Chofets Chaim commented that Hkb"h came down from heaven to earth teach us Torah so what's the big deal? Of course you would have to travel from America to Poland!
