In the early days of Oholei Torah, the Rebbe said R' Elye Chaim Roitblat should remain employed, even if not as a teacher, just for students to see him.
R' Pinye was that modern-day old-school eltere chossid who taught and inspired just by being.
He was my tutor in misivta ( as a Bocher I did not appreciate what I had). One thing I vividly remember that he thought me. I would always bring the Gemara close to me half on the table and half against my chest. He would push the table closer to me so that the whole Gemara was on the table. He explained, you need to bring your self to Torah, not the Torah closer to you.
