From The Urantia Book:
2:7.11 All truth—material, philosophic, or spiritual—is both beautiful and good. All real beauty—material art or spiritual symmetry—is both true and good. All genuine goodness—whether personal morality, social equity, or divine ministry—is equally true and beautiful. Health, sanity, and happiness are integrations of truth, beauty, and goodness as they are blended in human experience. Such levels of efficient living come about through the unification of energy systems, idea systems, and spirit systems.
