Negative shockwave theory
It's a bit like karma, only it works much faster. Say someone treats you in a way that's objectively wrong. That sends a wave of negativity through you and makes you want to "hit back", or something along those lines. And if you do "hit back" at that jerk, it feels like you can release that energy. Life goes on.
But if that wave of negativity comes and you choose not to "hit back", it creates a kind of vacuum that draws that negativity back into your life in reverse โ as positivity!
