10. Politeness (Teinei)
Politeness (Teinei) infused every aspect of samurai life, from high-stakes negotiations to simple daily interactions. This principle encouraged warriors to approach even delicate or hostile situations with grace and composure. Through carefully practiced etiquette, samurai could diffuse tension and resolve conflicts without unnecessary violence. Politeness also fostered mutual respect, smoothing relationships both within and beyond their ranks. By valuing courteous behavior, samurai maintained dignity in every encounter, proving that true strength is often revealed through restraint and refined conduct.
