What Is the I Ching (Yi King)?
The I Ching — also written Yi King, Yi Jing or Yijing — is the oldest text of Chinese civilization. Its name literally means "The Book of Changes". Oracle, book of wisdom and philosophical treatise, it has accompanied humanity for over 5,000 years.
Claimed throughout the ages by magicians and princes, priests and physicians, artists and philosophers, it has shaped the entirety of Chinese thought — from Confucianism to Taoism, from traditional medicine to martial arts.
A mirror of your present situation
The I Ching is not a book of predictions. It does not tell you what will happen. It shows you what is — the deep nature of your current situation, the forces at play, the transformations underway.
"The oracle does not predict a fixed future. It illuminates the present moment and the possible transformations."
Like a mirror, it reflects your question with sometimes disconcerting clarity. The emperors of China consulted the I Ching before every important decision. Generals consulted it before battle. Today, millions of people around the world continue to turn to it.
64 hexagrams: the language of the universe
The I Ching system rests on 64 hexagrams — figures composed of six stacked lines, either solid (yang ——) or broken (yin — —). Each hexagram represents an archetypal situation of human existence.
These 64 figures arise from the combination of 8 fundamental trigrams, created according to legend by the mythical sovereign Fuxi approximately 5,000 years ago:
- ☰ Heaven (Qian) — The creative force
- ☷ Earth (Kun) — Receptivity
- ☳ Thunder (Zhen) — Awakening, movement
- ☵ Water (Kan) — Danger, depth
- ☶ Mountain (Gen) — Stillness, meditation
- ☴ Wind (Xun) — Gentle penetration
- ☲ Fire (Li) — Clarity, attachment
- ☱ Lake (Dui) — Joy, openness
Each hexagram is the superposition of two trigrams — one for the bottom (the Earth, the inner world), the other for the top (Heaven, the outer world). This combination creates a complete picture of the situation.
Yin and yang: everything is in motion
At the heart of the I Ching lies the principle of yin and yang — two complementary forces in perpetual motion. Yin is not the opposite of yang; they are two faces of the same reality.
What makes the I Ching unique among the world's oracles is its dynamic vision of the universe. Nothing is fixed. Every situation contains within it the seeds of its own transformation. This is the very meaning of the word changes in the title.
"When the way reaches its end, then change; having changed, you pass through."
— I Ching, Hexagram 49
Moving lines: the future in motion
During a casting, certain lines may be moving — that is, in the process of transforming. A moving yang line (value 9, called "old yang") transforms into yin. A moving yin line (value 6, "old yin") transforms into yang.
These mutations generate a second hexagram — the perspective hexagram — which indicates what direction the situation is evolving toward. It is this temporal dimension that gives the I Ching its full richness.
Four major scholarly translations
The original text of the I Ching is written in archaic classical Chinese. Over the centuries, four major translations have made this wisdom accessible to the world:
- James Legge (1882) — The first scholarly translation into English, by the great British sinologist at Oxford. A rigorous academic approach.
- Paul-Louis-Felix Philastre (1885) — The first complete translation into French, of remarkable erudition. A text faithful to the Chinese tradition.
- Richard Wilhelm (1923) — The German translation that revolutionized the Western understanding of the I Ching. Prefaced by Carl Gustav Jung.
- Marie-Noëlle Doublet (2007) — A modern translation oriented toward personal development, accessible and contemporary.
Virtual I-Ching is the only application in the world that offers these four translations side by side, allowing an in-depth understanding of each hexagram.
How to consult the I Ching?
The traditional method used 50 yarrow stalks — a complex ritual reserved for initiates. In the fourteenth century, the Ming dynasty democratized the oracle by introducing the 3-coin method: simpler, faster, and just as profound.
Three coins are tossed six times. Each toss produces a line (yin or yang, moving or stable). The six lines form a hexagram — your answer.
Virtual I-Ching faithfully reproduces this method with two modes:
- Zen Mode — Local pseudo-random generator. Ideal for exploring and learning.
- Quantum Mode — Certified quantum generator (Quantum Blockchains, Poland). True randomness from quantum vacuum fluctuations.
The question, key to the consultation
The I Ching responds to the quality of your question. A sincere and open question calls for a deep answer. Avoid closed questions ("Am I going to win the lottery?"). Instead, try:
- "What is the nature of my current situation?"
- "How should I approach this relationship?"
- "What do I need to understand about this challenge?"
"Sincerity is the first condition of any consultation. The oracle answers those who question it with an open heart."
