Why: the Self doesn't create agency, actions, or the connection of actions with their fruits, nature alone functions in these ways, again separating the deepest sense of self from the machinery of cause and effect.

In life: you are not identical to every outcome your actions produce, some of that belongs to circumstances outside your authorship.

Teaching: when reviewing outcomes you're unhappy with, separate what was actually your responsibility from what belonged to circumstance, and only carry the part that's genuinely yours.
