Note 1. To the Subsection “1.1. Sungsang and Hyungsang”
A representative example of the reciprocal relationship is yang and yin, or man and woman. Exposition of the Divine Principle (hereafter cited as DP ) explains that the relationship between Sungsang and Hyungsang is, in a way, the same as that between Yang and Yin, or man and woman, as follows: i) “In this case, the yang and yin of God were manifested in masculinity and femininity” (DP , 19). ii) “Because God exists as the subject partner having the qualities of internal nature and masculinity, He created the universe as His object partner with the qualities of external form and femininity” (DP , 19). iii)
God is the Subject in whom the dual characteristics of original internal nature and original external form are in harmony. At the same time, God is the harmonious union of masculinity and femininity, which manifests the qualities of original internal nature and original external form, respectively. In relation to the universe, God is the subject partner having the qualities of internal nature and masculinity” (DP , 19). Consequently, the relationship of Sungsang and Hyungsang, and the relationship between God and the creation are also the reciprocal relationships of yang and yin.
