The oldest of the classics: a philosophy of flux.
A system of 64 hexagrams mapping how every situation changes into the next.

Each hexagram is six lines, broken or unbroken, that together describe a situation and its tendency to change. Consulting the I Ching is less about predicting the future than about seeing the present clearly as a moment in motion.
Its core goes back to Western Zhou divination around 1000 to 750 BCE. The Ten Wings commentaries, later attributed to Confucius, turned it into philosophy. Leibniz saw binary arithmetic in its broken and unbroken lines.
Complementary forces whose balance is always shifting.
Three lines; eight trigrams for heaven, earth, thunder, water, mountain, wind, fire, and lake.
The only constant. Every line, pushed far enough, becomes its opposite.
Three coins, six tosses. Sums of six and nine are old lines that change into their opposites, giving a second hexagram that shows where the situation is heading.
Hold a question in mind. Toss three coins six times; each toss builds one line, from the bottom up.
Heads count three, tails two.
Sixty-four situations, each changing into the next.
The I Ching was read less as fortune-telling than as a mirror for seeing the present clearly, as a moment in motion.
Each passage is cited and credited. Classical lines open character by character: the reading, the sense, and what is hiding inside a single character. Paraphrases are marked where the best translations are still under copyright.

In the system of the Yi there is the Grand Terminus, which produced the two elementary Forms. Those two Forms produced the Four emblematic Symbols, which again produced the eight Trigrams.

A three-thousand-year-old reminder that no situation is permanent, and that the right move depends on where you are in the cycle.
Map it onto your own decision
