數字易卦的源頭可上溯到八千年前。自伏羲時代經炎黃時代到夏商時代，數字易卦走過了它五千餘載的漫長歷程。從出土大量的確鑿的毋庸置疑的文物考古資料中，令人信服地說明：數字易卦本為易經的根基和來源，易經則為數字易卦的演變、發展、昇華和突變。二者之間是源和流的關係，是從漸變到突變的發展，是由量變到質變的必然。

　　　　　Yi Trigrams can be traced back to about eight thousand years ago. From the period of Fux Xi to the dynasties of Xia and Shang, yi Trigrams developed for more than eight thousand years. From the great number of tangible archelogical materials that have been discovered, we are convinced that Yi Trigrams is the foundation and source of Yi Jing, which is the evolution, development, sublimation and mutation of Yi Trigrams. The relation between the two is the development from gradual transformation to mutation, as well as the inevitability from the quantitative to qualitative changes.
