What is the relationship between the dual characteristics of internal nature and external form?

What is the relationship between the dual characteristics of internal nature and external form and the dual characteristics of yang and yin? God’s original internal nature and original external form each contain the mutual relationship of original yang and original yin. Therefore, original yang and original yin are attributes of original internal nature and original external form. The relationship between yang and yin is similar to that which exists between internal nature and external form. Yang and yin thus have the following mutual relationships: internal and external, cause and result, subject partner and object partner, vertical and horizontal. For this reason, it is written in Genesis that God took a rib from the man, Adam, and created a woman, Eve, to be his helper (Gen. 2:22). In this case, the yang and yin of God were manifested in masculinity and femininity.
