This thesis is a study of the first principle and phase of the universe, and it is a discussion of the theory of constant principle and the transformation of the universe into the shape of the gwaesang(卦象), and the theory of cosmology. There have been many studies of the reality and nature of the universe through ‘Hetu(河圖)’-‘Luoshu(洛書)’ and ‘I Ching(周易)’ by the numerous sages of Oriental origin. However, the ultimate power of the universe is the ultimate force, and its underlying strength has not helped explain the real shape of the change and how it produces and grows everything. But when Il-bu teaches Hwanggeuk(皇極), the concept of cosmology, Taegeuk(太極), and Hwanggeuk(皇極), the universe becomes more organized and well-organized, and it becomes more organized to organize and change all aspects of the universe. Looking at the Susang(數象), the Hetu represents a unified image, and the Luoshu shows the process of developing a substantial change in the development of a natural number. In other words, 'Hetu' is a unified unification, and 'Luoshu' is a merchant divided by fragmented division and unification. Therefore, one can find dispersion and unification of spring and summer, and the sideness movement of yin and yang from autumn and winter to unification. It is specifically effected by a variation of 'Yin and Yang and the Five Elements', 'Heavenly stem', and 'Earthly branch'. Thus, a three-way logic from ‘Hetu(河圖)’-‘Luoshu(洛書)’ to ‘I Ching’ and ‘Right Change(正易)’ enabled the study of The body of the universe and the ‘image’.
