When a person commits a sin and does not turn in repentance, when that person forgets the sin, the Holy One remembers it.

When a person fulfills a commandment by doing a good deed, the Holy One remembers it.

When a person commits a sin and later turns in repentance, remembering the sin, the Holy One grants atonement, and forgets the sin.

When a person fulfills a commandment and ius constantly filled with self-praise because of it, the Holy One forgets it.

What a person forgets, God Remembers; what a person remembers, God forgets.

—Rebbe Shmelke of Nikolsberg

This was a note included in the margins of our Machzor^*, and was pointed out during Rosh Hashanah services today by the Rabbi.

It needs to be shared.
