There were only very few who truly appreciated his depth. All However appreciated his greatness.
His Talmidim grew to become renowned Gedolei Torah. Amongst them the current Rosh Yeshiva of Rabbenu Chaim Berlin, Hagaon Rav Aharon Shechter, his son in law, Rosh Yeshivas pachad Yitzchok in Yerushalayim, Hagaon Rav Yonason David, Hagaon Harav Feivel Cohen, Hagaon Rav Hillel David, Hagaon Harav Yitzchok Soloveitchik, Hagaon Rav M. Belsky, the Noviminsker Rebbe, Hagaon Rav Zevulan Leib, Hagaon Rav Yehuda Edelman shlit"a, Hagaon Rav Shlomo Freifeld, Zt"l, and the two popular Askanim, R' Avrohom Fruchthandler, R' Tuvia Obermeister, and many others.
To listen to his Divrei Machshava was hearing the euphonic sounds of a merge between "Sechel" and "Regesh".
To him, pirsum was disdainful. In one of his popular Igros he makes a real strong statement about Mitzvos done with publicity.
Though he knew everything, he only used pure torah to communicate the important lessons of Torah.
His own personal growth was paramount. When after many years he was questioned about changing his mind about a certain idea. He responded "Vos Vilt Eer, Ich Zol Shtarben Vee Ich Hub Geboyrin Gevorin? I Changed my Mind".
When he was very ill, his nurse in the hospital in Israel tried to assist him to rest in a comfortable position. She asked him in Hebrew "Haim Noach Lecho?" To which he answered "Ani Kvor Ochez B'lech Lecha".
YEHI ZICHRO BARUCH!!!!!
