I Ching

Origin and etymology

The name Yì Jīng (易經) translates as "Book of Changes" or "Classic of Changes". Yì means transformation, mutation; Jīng is a classical or canonical book. Its traditional attribution divides authorship among four mythical sages: the legendary emperor Fu Xi (discoverer of the eight trigrams), king Wen Wang (11th century BC, author of the hexagram texts), the Duke of Zhou (line texts) and Confucius (the philosophical commentaries known as the "Ten Wings").

The I Ching is part of the Five Classics of the Confucian tradition and is one of the pillars of Chinese thought, alongside Taoism. In the 20th century, Carl Jung wrote the foreword to the Wilhelm translation (1923), introducing it to the West as a serious tool of psychological exploration. Its use is now global.

Structure of the system

The I Ching is based on 64 hexagrams, six-line figures (continuous or broken) that combine two trigrams of three lines. The eight trigrams (Bagua) represent elemental forces: Heaven, Earth, Thunder, Water, Mountain, Wind, Fire, Lake. Their combination yields the 64 hexagrams, each with a name (Qian = the Creative, Kun = the Receptive, Tai = Peace, etc.) and a main text with advice.

The most interesting technical detail is the changing lines: when a line is "in motion" (resulting from coin tosses), it generates a secondary hexagram showing where the situation is transforming. So you obtain two images: where you are now and where you tend toward. This ability to read the direction of change is the I Ching's distinguishing mark.

How it is consulted

Traditionally, 50 yarrow stalks were used in a meditative process of about 20 minutes. The most widespread method today is three coins: you toss three coins six times, noting heads/tails to build each line of the hexagram (from bottom to top). The digital method simulates the toss with the same statistical probability. It works exceptionally well for strategy questions: do I move forward or wait, how do I face this conflict, what stance do I take?
