<易經>子曰. 夫易何為者也, 夫易開物成務, 冒天下之道, 如斯而已者也, 是故聖人以通天下之志, 以定天下之業, 以斷天下之疑. <The Text of Yi King>The Master said: What is it that the Yi does? The Yi opens up (the knowledge of the issues of ) things, accomplishes the undertakings of men, and embraces under it( the way of) all things under the sky. This and nothing more is what the Yi does. Thereby the sages, through (divination by) it, would give their proper course to the aims of all under the sky, would give stability to their undertakings, and determine their doubts.
