I Ching (Yijing)

Overview & Historical Origins

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:

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

Key Components & Structure

The Eight Trigrams (Bagua)

The foundation of the I Ching consists of eight trigrams, three-line figures representing fundamental forces of nature and aspects of reality:

Trigram Name Image Attribute Family Direction
Qián (乾) Heaven Creative, Strong Father Northwest
Kūn (坤) Earth Receptive, Devoted Mother Southwest
Zhèn (震) Thunder Arousing, Moving Eldest Son East
Kǎn (坎) Water/Abyss Dangerous, Abysmal Middle Son North
Gèn (艮) Mountain Keeping Still Youngest Son Northeast
Xùn (巽) Wind/Wood Gentle, Penetrating Eldest Daughter Southeast
Lí (離) Fire Clinging, Luminous Middle Daughter South
Duì (兌) Lake/Marsh Joyous, Pleasing Youngest Daughter West

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:

Practice & Methods

Traditional Methods of Consultation

Yarrow Stalk Method (Shì Fǎ)

The classical method using 50 yarrow stalks (one set aside, using 49):

  1. Begin with 49 stalks, divide randomly into two piles
  2. Set aside one stalk from the right pile
  3. Count out the left pile in groups of four; remainder goes between fingers
  4. Count out the right pile in groups of four; remainder goes between fingers
  5. Combine remainders (will equal 5 or 9)
  6. Repeat this process three times to determine one line (6, 7, 8, or 9)
  7. 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:

  1. Use three identical coins (traditionally Chinese coins with inscription)
  2. Assign values: Heads = 3 (yang), Tails = 2 (yin)
  3. Toss three coins simultaneously
  4. Sum the values: 6 = changing yin, 7 = stable yang, 8 = stable yin, 9 = changing yang
  5. Record the line (broken for yin, unbroken for yang)
  6. 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:

  1. Primary Hexagram: Read the Judgment and Image for overall situation
  2. Changing Lines: Read the line texts for any moving lines (bottom to top)
  3. Relating Hexagrams: If multiple lines change, sometimes read only top and bottom
  4. Future Hexagram: Transform changing lines to create the resultant hexagram
  5. Synthesis: Integrate all readings into coherent guidance

Formulating Questions

The quality of the question significantly affects the usefulness of the response:

Ethical Considerations

Traditional practice emphasizes approaching the I Ching with sincerity and respect:

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:

Taoist Interpretation

Taoist readings emphasize spontaneity, naturalness, and wu wei (effortless action). Rather than moral prescriptions, Taoist interpretation focuses on:

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:
