The central purpose of the divine religions is the establishment of peace and unity among mankind. Their reality is one; therefore, their accomplishment is one and universal—whether it be through the essential or material ordinances of God. There is but one light of the material sun, one ocean, one rain, one atmosphere. Similarly, in the spiritual world there is one divine reality forming the center and altruistic basis for peace and reconciliation among various and conflicting nations and peoples.
