Great question dude.
Non duality isn’t exactly complete passiveness. It’s a matter of more choice from being able to see both perspectives at once rather than stuck on one side or the other. If you don’t have much of an ego, then you often end up choosing what has the better outcome for the collective and creates the most overall balance. Egoless people tend to be utilitarian. But… they might choose not act at all. Non-duality is to gain the free will of choice rather than be subjected to the choice of your ego’s beliefs/perspective. And in this free will, you do gain a strong clarity as to what course of action can lead to the most balance.
