The Maharil's Birkas HaTorah

Rav Yosef Chaim Scheinberger related that he once watched the Maharil Diskin say birkas haTorah when he was honored with an aliyah. As the Maharil made the berachah, he was so aflame that he looked as one might imagine the Kohen Gadol looked when he pronounced the Divine Name, his face burning like a pillar of fire.

The Rav brought such intensity of awe to the moment that the sinews and veins of his face stood out. The sight made such a strong impression that its effect lasted for half a year.
