Once Rav Sternbuch was at the Brisker Rav’s house when a Rav came in and spoke with admiration about a certain talmid chacham, saying that he was a tzaddik. The Brisker Rav responded, “I don’t know if he is a tzaddik, but one thing I do know: he is a masmid, and as far as I’m concerned, the greatest form of tzidkus is hasmadah (di greste frumkeit is hasmodo)”.
