The I Ching and T'ai Chi Ch'uan

· A systems approach for practitioners

Abstract

The I Ching is not a fortune-telling book. Its oldest layer, the Zhouyi, was a Bronze Age decision-support system: a way to diagnose the current configuration of forces and how they tend to evolve. Because it describes how change behaves rather than any particular content, it maps naturally onto T’ai Chi Ch’uan. This handout separates the text’s three layers, then builds up from yin and yang as receiving and manifesting, through the eight trigrams as behavioral modes, to hexagrams as system states, and reads “stand like a great mountain, flow like a great river” as a precise instruction to run several modes at once.

A handout for students of T’ai Chi Ch’uan in the Cheng Man-ch’ing lineage. Eight pages, February 2026.

Contents

  1. What the I Ching actually is. A Bronze Age systems-analysis engine, not an oracle.
  2. Which I Ching are you reading? The original Zhouyi, the Confucian Ten Wings, and the Daoist layer, and why the difference matters.
  3. Yin and yang: receiving and manifesting. The two modes of any living system, and the whole alphabet of the book.
  4. The eight trigrams. Each one a behavioral mode, and what it looks like in the body.
  5. From trigrams to hexagrams. Sixty-four system states, and why the transitions between them are where T’ai Chi lives.
  6. “Stand like a great mountain, flow like a great river.” A koan, and what the trigrams reveal about it.
  7. The T’ai Chi body as a trigram system. Peng, song, listening, yi, root, fa jin, long power and connection, mapped to the eight trigrams.
  8. Internal connections. The same yin/yang logic in the psyche.
  9. For further study. Texts, and a practical exercise for standing and form work.

It opens with a note worth repeating: the handout was developed with AI tools, which confidently got trigram structures wrong more than once until they were checked against the book. Always verify against primary sources.
