This is another not-new insight, but one that becomes very clear through different forms of inquiry:
When I suffer, it is because I am willing to pay the price of suffering to be right.
Or rather, to be right in the sense of holding onto one story as right and its reversals as wrong, taking it as an exclusive truth.
The belief has a shadow, which is the truth in all of its reversals, and also the inherent neutrality of the situation which is revealed when the relative truths in all the reversals cancel each other out. And this shadow is what creates the suffering.
Life shows up in ways that correspond to the shadow rather than the original belief, there is a dissonance, and suffering.
