 With trigrams and hexagrams as symbols of the “three potencies”, the starting point of Yijing philosophy is the acceptance of human finitude. On the one hand, the “three potencies” highlight the limits of human beings in shaping the natural environment. On the other, they empower human beings to pursue their goals if they are willing to adapt to the natural environment. For instance, in Xici (one of the “Ten Wings”), the authors point out that in the oracles there were encouraging words such as “auspicious” (ji) and “without blame” (wujiu), and stern warnings against “calamity” (xiong), “blame” (jiu), “regret” (hui) and “remorse” (lin) (Xici I: 3, 7). These contrasting prognostications highlight the harsh reality of human existence. In some incidents, the wind of luck is on our side; whatever we do seems to go well. But in other incidents, we are clearly out of luck: no matter how hard we try, we are doomed to failure.
