In some sense I don’t think spiritual-style acceptance and change the world style agency conflict at all. The former refers to stopping subsecond micro-physiological* moments of resistance that causes essentially all suffering, the latter longer timescales of building new things etc
but also most people when they taste happiness independent of conditions lose their drive for a while. They also realized they never really needed the things they were building, which were symptomatic treatments to feeling bad or disconnect or worthless etc rather than cures. They were only changing the world because they personally wanted to feel good, even though they couldn’t admit that to themselves until they finally had it. So you need to reboot the system based on something else, like helping others or simply curiosity, which is possible but from what I’ve seen usually takes some time
* I think it’s a bit of an open question to what extent it’s actually physiological vs “mental”, but even if it’s mental it feels so close to being muscular it might be easier to think of it that way
