 To support absolutism, Han commentators transformed the Yijing into a cosmological manual reflecting the ebb and flow of cosmic forces. They earnestly reorganized the hexagram sequence to match the cosmic rhythm, demonstrating that the natural and human realms are one and the same. Although most of the writings of the Han commentators are lost, in an 8th-9th century text, Zhouyi jijie (A Collection of Explanations on the Changes of Zhou Dynasty) edited by Li Dingzuo, we have glimpses of the ambition of the Han commentators who spent their lives fathoming the cosmos and ordering the world (R. Smith 2008: 57–88).
