4. Respect (Rei)
Respect (rei) defined the way samurai engaged with others—through careful etiquette and sincere politeness. This code extended from the battlefield, where honor was shown even to opponents, to daily interactions with peers and superiors. By adhering to rituals of respect, samurai fostered discipline, trust, and harmony within their ranks. Such practices helped maintain order and unity, reinforcing the social fabric of the warrior class.
