Five highlights from the life of the Tzaddik and Gaon Rov Dovid Povarski ztz"l [Rosh Yeshivas Ponovitch]:
He once gave shiur even though he was breathing through an oxygen mask.
He gave shiur in an orchard during the War of Independence as bombs were flying overhead. He didn't seem to notice.
He was once ill so his wife hid his shoes so that he wouldn't go to yeshiva. He went in his slippers.
He heard that the boys were preparing for the Purim festivities and couldn't understand. He heard of preparing for Rosh Hashana, but preparing for Purim??
He said that from the age of thirteen if he ate fruits or dirt it was the same for him. He just didn't care.
If you want to get to know the man read his approximately 25 volume set "Shiurei Rabbeinu Dovid".
זכות הצדיקים יעזור ויגן ויושיע!!
