The I Ching (Wade-Giles romanization) or Yijing (Pinyin), known as the Book of Changes, is one of
the oldest Chinese classical texts and divination systems, with origins dating back over 3,000 years
to the Western Zhou Dynasty (1000-750 BCE) and possibly earlier. It consists of 64 hexagrams, each
composed of six stacked lines that are either broken (yin) or unbroken (yang), representing the
fundamental binary forces underlying all existence.
The text evolved through several historical layers: the hexagrams themselves (believed to derive from
even older divination practices using oracle bones and turtle shells), the brief hexagram and line
statements attributed to King Wen and the Duke of Zhou, and later philosophical commentaries known
as the Ten Wings, traditionally attributed to Confucius but likely compiled by his followers during
the Warring States period (475-221 BCE).
Cultural Significance
The I Ching occupies a unique position in Chinese thought as both a divination manual and
a philosophical text. It influenced both Confucianism (emphasizing moral development and
proper social conduct) and Taoism (focusing on natural harmony and spontaneous action).
Neo-Confucian scholars in the Song Dynasty (960-1279 CE) developed elaborate cosmological
interpretations linking the hexagrams to metaphysical principles.
Core Philosophy: Change and Transformation
The central principle of the I Ching is that reality is not static but constantly transforming
according to natural patterns. Change occurs through the dynamic interplay of yin and yang:
Yang (—): The creative, active, masculine, bright, firm, heaven principle
Unlike Western binary opposition, yin and yang are complementary forces that transform into each
other. The hexagrams capture moments in this continuous cycle of transformation, providing insight
into the present situation and indicating how change is likely to unfold.
Purpose and Applications
Divination: Receiving guidance on specific questions or situations
Philosophical Study: Understanding the principles of change and cosmic order
Meditation: Contemplating the hexagram images and judgments
Decision-Making: Gaining perspective on timing and proper action
Self-Cultivation: Aligning oneself with natural processes and moral development
Strategic Planning: Assessing situations in business, politics, and warfare

The 64 Hexagrams
Hexagrams are formed by stacking two trigrams (lower and upper), creating 64 possible combinations
(8 × 8). Each hexagram has a number, name, image, judgment, and commentary on each of its six lines.

Structure of Each Hexagram
Every hexagram entry in the I Ching contains several components:
Number and Name: Sequential position (1-64) and Chinese name with translation
Symbol/Image: Natural imagery associated with the trigram combination
Judgment (Tuàn): Overall assessment of the hexagram's meaning
Line Texts: Six individual statements for each line position
Changing Lines: Indications of transformation to other hexagrams
Practice & Methods
Traditional Methods of Consultation
Yarrow Stalk Method (Shì Fǎ)
The classical method using 50 yarrow stalks (one set aside, using 49):
Begin with 49 stalks, divide randomly into two piles
Set aside one stalk from the right pile
Count out the left pile in groups of four; remainder goes between fingers
Count out the right pile in groups of four; remainder goes between fingers
Combine remainders (will equal 5 or 9)
Repeat this process three times to determine one line (6, 7, 8, or 9)
Repeat entire process six times to build the hexagram from bottom to top
This elaborate process takes 15-20 minutes and creates a meditative state conducive to
receiving insight. The method produces probabilities that favor certain line values,
which traditional practitioners consider cosmologically significant.
Three Coin Method
A simplified method that became popular during the Han Dynasty:
Use three identical coins (traditionally Chinese coins with inscription)
Assign values: Heads = 3 (yang), Tails = 2 (yin)
Toss three coins simultaneously
Sum the values: 6 = changing yin, 7 = stable yang, 8 = stable yin, 9 = changing yang
Record the line (broken for yin, unbroken for yang)
Repeat six times, building from bottom to top
While faster than yarrow stalks, this method produces different probabilities for
changing versus stable lines.
Interpreting the Response
Changing Lines
Lines valued 6 or 9 are "changing" or "moving" lines—they represent unstable
situations in transformation. A line 6 (old yin) transforms into yang; line 9
(old yang) transforms into yin. These changing lines indicate which line texts
to read for specific guidance, and they generate a second hexagram showing the
situation's likely development.
Reading Strategy
The traditional approach to interpretation involves multiple layers:
Primary Hexagram: Read the Judgment and Image for overall situation
Changing Lines: Read the line texts for any moving lines (bottom to top)
Relating Hexagrams: If multiple lines change, sometimes read only top and bottom
Future Hexagram: Transform changing lines to create the resultant hexagram
Synthesis: Integrate all readings into coherent guidance
Formulating Questions
The quality of the question significantly affects the usefulness of the response:
Be Specific: "How should I approach this job opportunity?" rather than "What about work?"
Focus on Understanding: "What do I need to know about..." rather than "Will I..."
Request Guidance: "What is the best approach to..." rather than yes/no questions
Timing Questions: "Is now the right time to..." acknowledges the I Ching's emphasis on timing
Single Focus: One clear question per consultation rather than multiple topics
Ethical Considerations
Traditional practice emphasizes approaching the I Ching with sincerity and respect:
Don't consult frivolously or repeatedly on the same question
Maintain a receptive, contemplative state rather than demanding answers
Accept challenging or unexpected responses
Use insights to inform decisions rather than abdicate responsibility
Consider the oracle a teacher, not a fortune-telling device
Traditions & Variations
Philosophical Schools
Confucian Interpretation
The Confucian approach emphasizes moral development, social harmony, and proper conduct.
The Ten Wings commentaries interpret hexagrams as guidance for ethical behavior, self-cultivation,
and fulfilling one's role in society. Key concepts include:
Alignment with the "Mandate of Heaven" (Tianming)
Development of virtue (de) through proper action
Recognition of one's position in the social and cosmic order
Timing actions according to natural cycles
Taoist Interpretation
Taoist readings emphasize spontaneity, naturalness, and wu wei (effortless action).
Rather than moral prescriptions, Taoist interpretation focuses on:
Flowing with circumstances rather than forcing outcomes
Recognizing the natural tendency of situations to transform
Understanding when to act and when to refrain
Maintaining balance and avoiding extremes
Neo-Confucian Cosmology
Song Dynasty scholars like Shao Yong developed elaborate metaphysical systems based
on the I Ching, connecting hexagrams to the generation of reality itself through
the Supreme Ultimate (Taiji) differentiating into yin and yang, then into four
symbols, then eight trigrams, then 64 hexagrams—a cosmogonic sequence.
Western Adaptations
Jungian Psychology
Carl Jung introduced the I Ching to Western psychology, interpreting it through his
concept of synchronicity—meaningful coincidences that reflect the archetypal structure
of the collective unconscious. Jung saw hexagrams as representing universal psychic
patterns, making consultation a method of accessing unconscious knowledge.
Wilhelm-Baynes Translation
Richard Wilhelm's German translation (1923), later rendered into English by Cary Baynes
(1950) with Jung's foreword, became the standard Western version. Wilhelm studied with
Chinese scholars and incorporated both Confucian and Taoist perspectives, making the
text philosophically rich though sometimes departing from literal translation.
Contemporary Interpretations
Modern Western practitioners have developed various approaches:
Psychological Tool: Using hexagrams for self-reflection and decision-making
Creative Inspiration: Artists and writers consulting for creative direction
Business Strategy: Corporate consultants applying I Ching principles to management
Simplified Systems: Apps and online consultations using random number generation

sounds) to generate hexagrams spontaneously without coins or yarrow stalks.
