The development of an esthetic conscience creates the need to put away even the shoes of others if they are not in their proper place. If we thank the sempai for his or her teaching, he or she will be happy. Respect towards the sempai must not be provoked, the kohai must naturally want to respect the sempai. The spirit of gratitude, respect and gratefulness is naturally felt by the other when it fills the etiquette. Etiquette thus governs the mutual relations.
Hierarchy naturally falls in place when etiquette is respected.
Etiquette must be the expression of the heart's humanity. It's not enough to simply yield to the form. If respect doesn't inhabit the heart, the form will be an empty shell with no soul. We must respect the personality of the other. Actions in accord with the rules of etiquette breed a pure heart and a noble attitude.
