Rav Yissochor Dov on Rav Aharon

Rav Yaakov Yosef of Skver used to relate how Rav Yissochor Dov of Belz would be seized with awe whenever he spoke about the Tzaddik, Rav Aharon of Czernobyl. He would shake and tremble and become covered in goosebumps, and those around him had to dress him in a warm fur coat, because his teeth rattled and his limbs shook.

Rav Yissochor Dov would then tell how Rav Aharon would awaken early and recite Birkas HaShachar with such intensity that all present could see the Shechina descend upon him. He also told how, as Shabbos Kodesh approached, Rav Aharon's eyes would shine and glow with the kedusha of Shabbos.
