Context: In randori we learn to employ the principle of maximum efficiency even when we could easily overpower an opponent. Indeed, it is much more impressive to beat an opponent with proper technique than with brute force. This lesson is equally applicable in daily life: the student realized persuasion backed up by sound logic is ultimately more effective than coercion.
