“Therefore, the eight trigrams are frequently coordinated with the day, and they can of course also be correlated with the course of the year. ... A cycle of twelve hexagrams from the Book of Changes, the so-called P'i Kua is often also correlated witht he course of the year. ... These eight trigrams, then are coordinated with the times of the day and the cardinal points, and have, in addition, very interesting psychological correlations.”

“There are many indications that the hexagrams were the original images from which the trigrams were then later abstracted and that the configurations of double lines are derrived from a still later anaysis.”

“The situations depicted in the Book of Changes are the primary data of life -- what happens to everybody, every day, and what is simple and easy to understand.”

“(T)his is precisely the importance of the world-view described in the Book of Changes: there is no situation without a way out. All situations are stages of change. Therefore, even when things are most difficult we can plant the seed for a new situation that will preserve within itself the present situation, though we must be capable of adapting and finding the proper attitude.”

“Therefore, it is believed that the ancestors return after a lapse of tiem as if to a general and spiritual reservoir from which they will sooner or later unite once more with human bodies and human souls as their stimuli and impulses to life. ... Such is more or less the idea of Confucianism. And the only exception is that all human beings are not viewed as equally immortal. Whoever has harmonized his nature and caused his existence to be so effective as to emanate magical powers because they can transform and act creatively, such a person will not return after death. He will not be a Kuei, but a Shen. Shen means someone divinely effective -- man as hero, who is connected with the entire cultural complex. The duration of the culture is also his duration, because his life endures in the pantheon of this culture.”

“It is no accident that, of the early Jesuit scholars who were pioneers in making China's culture known in Europe, those who concerned themselves with the Book of Changes were all later declared to be insane or heretic. Indeed, to the Chinese themselves the study of the I Ching is not to be taken lightly. By an unwritten law, only those advanced in years regard themselves as ready to learn from it. Confucius is said to have been seventy years old when he first took up the Book of Changes.”

“To become aware of what is constant in the flux of nature and life is the first step in abstract thinking. The recognition of regularity in the courses of the heavenly bodies and in the succession of seasons first provides a basis for a systematic ordering of events, and this knowledge makes possible a calendar. ... Simultaneously with this concept, a system of relationships comes into the idea of the world. Change is not something absolute, chaotic, and kaleidoscopic; its manifestation is a relative one, something connected with fixed points and a given order.”
