According to the teacher of the Unification Principle, a spirit man can easily reach stars which are at a distance of several hundred thousand or several million light years away. The motivating force behind astronomical research is to make space serviceable to human life. Thus each thing's ultimate purpose for the whole is to be of service to human life in some way. Let us discuss man's being the center of the macrocosm from a different aspect. Consequently, the purpose of the universe's existence centered on man is to return joy to God, the Creator.
Every being has a dual purpose.
One purpose pertains to internal character and the other to external form. The relationship between the two is exactly the same as that between character and form in any individual being. The purpose pertaining to the internal character is for the whole, while the purpose pertaining to the external form is for the individual. In other words, the former and the latter relate to each other as cause and effect, internal and external, and subject and object. Therefore, there cannot be any purpose of the individual apart from the purpose of the whole, nor any purpose of the whole that does not include the purpose of the individual.
