What is the I Ching? The Book of Changes
The I Ching (Book of Changes) is a 3,000-year-old Chinese classic and the oldest known oracle text. Its method is beautifully simple: cast three coins six times, and the six resulting lines — each yin or yang — form a hexagram. Each of the 64 hexagrams carries a name, a judgment and a layer of wisdom, and "moving" lines transform it into a second hexagram showing where the situation is heading.
Yin, yang and the six lines
A solid line is yang (active, light); a broken line is yin (receptive, still). Six lines stack bottom-up, and each position has meaning: the bottom line is the beginning, the top line the outcome, and the middle lines the journey in between.
The 64 hexagrams
Each hexagram is a pair of trigrams — eight basic three-line patterns for natural forces like Heaven, Earth, Thunder and Water. Their 64 combinations cover the situations of life: beginnings, conflicts, unions, standstills and breakthroughs, each with a name like "The Creative" or "Peace".
Moving lines and the transformed hexagram
A coin cast totalling 6 or 9 creates a "moving" line — the situation's pivot point. Moving lines flip to their opposite, forming the transformed hexagram: the main hexagram answers the present, the transformed one shows the trend. Our tool marks moving lines in red and explains each one's position.
FAQ
What question should I ask?
An open, present-tense question works best — "What should I focus on in my career?" rather than yes/no questions. Hold it in mind, then cast.
Are the coins really random?
Yes — the method is honest chance. The tradition's value is in pausing, focusing your question, and reading the answer as a fresh perspective rather than a verdict.
