Harmony is the balance of all people living sanctimoniously with one another in a Reiki energy of peace. Trust is where everyone in that society is treated fairly and given their fair dues by those who govern and have charge over specified affairs. And principle is when everyone in this society somehow suggests that they must always do the right thing.
Agreements that convey this message responsibly are the cornerstone of an established and truly illustrious society. This type of community agreement will see richness and prosperity working for all in the community and stand as an established and beloved institution of community spirit.
