Abstract
The best life is realized when all existents are in such harmony with one another that all can play their assigned roles. Suffering always comes from disharmony. The vital harmony of life is harmony between creatures and Creator; and the way in which a creature fits with the existence of the Creator is a necessary condition for the creature's survival. Among all creatures, human beings are able to have comprehensive knowledge of God and achieve an active harmony with God in all aspects. The earth is a testing ground in which humans can prepare themselves epistemically and then practically to contribute actively to harmony with God. Since a laboratory has its own rules, we should not expect an ideal life in the earthly laboratory. After the laboratorial role that one plays in the present world, one still is on the watch and can share in the experiences of living people and develop epistemically so that one receives an epistemic safe point that is necessary for harmony with God.
