He who angers you conquers you.

The aphorism warns that losing one’s temper hands power to an opponent: if someone can provoke you into anger, they can steer your attention, judgment, and behavior. “Conquers” is psychological rather than physical—anger narrows perception, invites rash speech or action, and can make a person easier to manipulate. Read this way, the line advocates emotional self-command as a form of autonomy and resilience. It also implies a strategic ethic: refusing provocation denies adversaries leverage and preserves one’s capacity to respond deliberately rather than reactively.
