I’m fairly certain that in the vast majority of the time, negative emotions are ego-dystonic.
They’re not something actively sought out out of a desire for meaning, they’re something essentially inflicted upon the sufferer by parts of their mind that they can’t control.
I think acceptance of negative emotion is often driven from being in that position, a position of helplessness, often driven out of a desire to maintain a good self-image, and avoid entering the negativity loop — and not from a position of having control over whether it happens or not, and seeking it because it brings meaning.
Yeah, it would be interesting to investigate how that would work. I think the insights would serve to set a lower bound to mood, the same as what religion does for many people.
I get bodily fatigue when I don’t take it for over five days, I haven’t ventured farther than that. No particular reason to.
