Q. I truly wonder since we daven for everything and our Tefilos have blessings for every need, how come we don’t have any prayer for having a good memory that is so essential!
A. Horav Aharon Miller Shlit’a pointed out that there is indeed a brocho for it in our common Shemone Essreh. It is included in the fourth blessing of “Atto Chonnen” in which we pray for wisdom, intelligence and understanding.
The Rov quoted Rashi (Avoda Zarah 8a) that mentions; “If one discovers that he cannot remember his learning, he may petition (for an improved memory) on the (fourth blessing of Shemoneh Essrei) “Atta Chonen,” or “He who grants knowledge.”
