My apologies for the conceptual hop.

This still leads to the same issue in >>158337
which could quite likely be extended to all emotional states, and lo, possibly much further as I hinted at with the Supersymmetry image.
To elucidate, it seems to me that emotional states of being sit on a spectrum. Removing one side is impossible, you can’t have one without the barometer of the opposing emotion, these things after all are quantities of chemicals. To some degree one can move the pointer along it’s positive axis, how one affects this desirable inclination is related to a combination of factors; genetic disposition, environment, and as you correctly state memory. We don’t have control over our genes beyond pre-emptive techniques and questionable crispr activities. Environment is sometimes out of our control especially for the unfortunate. Memory is something we can have a say in.
It’s my view that if we fill our life with good actions we accumulate a corpus positive memories increasing there probability of selection whence adhoc recollection occurs; this pushes the typical location the pointer toward the desirable side of the spectrum. Of course memories have differing strengths of imposition and in severe cases I feel introducing concepts such as thank-fullness and forgiveness in both the physical and metaphysical sense play out well.
I’m typically cognisant of not delving too deeply into discussing these areas as many people (including your past self) reject these types of ‘spiritual’ propositions, failing to see that at their core are cognitive models, techniques, practices, and ideas based upon several millennia of observational human study.
For example, the scientific community has rather recently understood the underlying mechanisms and benefits of fasting, of which society has partaken in as a spiritual rite for some time. It even feels weird to type fasting and science on the same line. The question arises what other overlaps exist in these arenas which have been sidelined, will prayer and meditation be future scientific revelations?
