Su Jun held a distinguished position as a prominent Yi-ologist in the
mid-Ming Dynasty and authored Yi Jing Ershuo and Yi Jing Shengshengpian.
Ershuo drew upon an extensive inheritance of Cheng Zhu’s concepts, blending
his own ideas with those of previous sages and providing a comprehensive
explanation of the classics and annotations. The meticulous elaborations provided
therein facilitate a comprehension of the complete interpretation of the classics
and judiciously select the insights offered by previous scholars. Shengshengpian
was composed subsequently, building upon the foundations laid by Ershuo.
This book further developed Zhu Xi’s Four Saints of Yijing learning, the theory
of symbol divination, and hexagram changes. It also provided profound insights
into the essence of the Dao of Life. As the culmination of Su Jun’s lifelong
scholarly pursuit, it holds a prominent position in the domain of Yi learning.
To grasp a comprehensive understanding of Su Jun’s Yijing scholarship, it
was imperative to peruse both of his works in conjunction. These books unveiled
three pivotal stages in Su Jun’s extensive journey of Yi exploration. Firstly, he
meticulously advanced his comprehension of Yi from its rudimentary aspects,
drawing from diverse perspectives, and expounding on Yin and Yang changes.
Secondly, he delved into the metaphysical Dao of Yi, immersing himself in its boundless potentialities. Thirdly, he inquired into the principles governing the
Dao of Life, recognizing the amalgamation of Yin and Yang transformations and
the perpetual growth of life. This process exemplified the complete evolution of
Yijing’s development, from the shallow to the profound. Through his in-depth
study of Yijing learning and integration of the previous scholars’ sayings, Su
Jun presented valuable and profound achievements in his Yijing learning studies.
