It’s not the blow that hurts, but your resistance to falling.
Even oaks need forests.

Marcus Aurelius Meditations 2.11: You could leave life right now. Let that determine what you do and say.
Calm isn’t the absence of chaos, but mastery over it.
Control your breath, and the world stops shaking you.
Epictetus Enchiridion 1: Some things are within our power, while others are not.
