For man, it is woman. Man and woman can find true love only through each other. In history, differing views of life, the universe and God have presented unresolved problems. The solution to these problems is to be found when true man and true woman unite with God in true love, creating absolute oneness. This is the source of absolute value.
Man exists for the sake of woman.
Woman exists for the sake of man. Each is to be the object of love of the other. God is a being of absolute love. He wanted to create objects of love, human beings, upon which He can pour out his love. In doing so, He would naturally look forward to the return of that love from men and women.
