Every man should act like this: when he meets a person more qualified than himself, he should be very pleased; when he meets someone less qualified than himself, he should be compassionate toward him; and when he meets someone equal to himself, he should make friendship with him. In this way one is never affected by the threefold miseries of this material world.
