Every aspect of Hashem’s creation bespeaks of perfection.
That’s the blueprint.
From the perspective of functionality, however, the gears of Creation only mesh if used for their intended purpose. When the sundry elements of Hashem’s mosaic are working at cross purposes the ink on Divine blueprint runs a little, for as Rav Avigdor Miller z”l was wont to say, the function of teeth are to chew one’s food, not the inside of the cheek.
The same holds true for forgetfulness.
Contrary to popular belief, the act of forgetting is not something that denotes some slight slippage that just happens on occasion in contradistinction to remembering which we view as the norm. It is also one of Hashem’s creations and it is not a physical process.
As Rav Miller z”l tells us, it is one of the wonderful mechanisms that the Creator put into the mind.
He wants you to forget.
There used to be a saying that there was no such thing as a free lunch in this world, the meaning of which was that every benefit in the here and now of this world came with a price tag of some kind, be it economic, emotional, spiritual or anything else upon which a demand could be made for a benefit received.
The act of forgetting is the only exception to this rule because this wonderful gift of forgetfulness is one of Hashem’s great kindnesses, and as pure chesed it demands nothing in return. It acts as the ultimate filter in that it retrospectively flattens life’s speed bumps or better yet deletes them altogether from the hard disk in our head.
Any emotionally healthy individual who has ever lost a loved one has tasted of the miracle of forgetfulness. At first, all of the beautiful memories are interlaced with the intense pain of the loss. But as time passes through the shiva, the shloshim, and the first year and beyond, it takes with it the edge off the emotional pain, and as such, what began as bittersweet memories morph into sweet memories at a given point in the timeline that stretches from the loss incurred into the future, with that time being different for each person. At this point, one’s memories of the past invoke a smile rather than a tear.
But as Rav Miller z”l reminds us, this gift of forgetfulness was given for a purpose, and it’s meant to be used for that purpose, and that purpose only.
You’re not supposed to forget Who gave you the gift. For that you are supposed to make use of that other great gift:
Remember Hashem your G-d.
