PATIENT
The I Ching (Yijing)
CORE MATERIAL
c. 1000 BCE
COMMENTARY
The Ten Wings, 4th–3rd century BCE
SYSTEM
8 trigrams, 64 hexagrams
CHIEF COMPLAINT
What is actually going on in this situation, and which way is it moving?
HISTORY OF PRESENT ILLNESS
One of the oldest books in continuous use. It is three things at once: a divination system you consult with a question, a philosophy of change, and a map of the patterns of human situations. The Ten Wings, traditionally attributed to Confucius and now dated to the 4th–3rd century BCE, turned a divination manual into a philosophy about change, ethics and the structure of reality. It is not read sequentially but consulted. You bring a question, you receive a hexagram, and the hexagram describes the pattern of your situation. The guide is clear that it does not predict the future; it maps the present with enough clarity that a path becomes visible.
REVIEW OF SYSTEMS
YIN AND YANG
Not opposites in conflict but complementary aspects of one dynamic process, each containing the seed of the other. When yang reaches its greatest strength, yin is born.
TRIGRAMS
Three lines; eight in all: Heaven, Earth, Thunder, Water, Mountain, Wind, Fire, Lake. The family of Qian and Kun and their six children.
HEXAGRAMS
Two trigrams stacked, 64 in all. Each has a name, a judgment, and six line statements.
TIMING
The same action that is wise in one moment is foolish in another. The I Ching gives situational guidance, not universal prescriptions.
THE JUNZI
The exemplary person, defined not by birth but by their relationship to change.
PHYSICAL EXAM — STYLE & STRUCTURE
- —Yarrow stalks take 30–45 minutes and were considered more meditative. The coin method is faster and most common today.
- —Six lines are built from the bottom up. Old lines (6 and 9) change into their opposite and produce a second hexagram.
- —The book ends with Before Completion, not After Completion: there is no final state, and every completion contains a new beginning.
- —The Confucian tradition discouraged consulting it for trivial matters.
- —It also doubles as a mirror: you cannot consult it without revealing something about yourself in the quality of the question. The danger the guide names is dependence.
ASSESSMENT & PLAN
Read the orientation and the Great Commentary first, then try casting once with a question that matters. Use the piece below, then look up the result in a translation. It is a non-denominational reference guide, and the full guide recommends Richard Wilhelm / Cary Baynes (Princeton), plus Thomas Cleary and Alfred Huang.
