64 Hexagrams

The 64 hexagrams of I Ching are binary lines arranged in a specific sequence. The first hexagram consists of six solid lines, and then we get all possible combinations of solid and broken lines, until reaching all broken lines in hexagram 64. After reading this article you will know what a solid/broken line is, how three lines become a trigram, two trigrams a hexagram, and then how the hexagrams are arranged as a whole in the legendary I Ching.

I Ching Lines are Binary Code

The binary system is at the core of this arrangement. In binary code, the digits are represented by 0s and 1s, the simplest yin and yang expressions. In I Ching, each of the 64 hexagrams is made up of six lines. A line is either solid (yang) or broken (yin). This binary representation allows for 64 possible combinations, hence the 64 hexagrams.

Each Hexagram is Two Trigrams

Each hexagram is built from the ground up and is formed by combining two trigrams: the lower trigram and the upper trigram. Each trigram consists, as the name implies, of three lines. The lower trigram, placed at the bottom of the hexagram, represents the inner or foundational aspects of the situation. In contrast, the upper trigram, positioned at the top, symbolizes the outer or developing aspects. The combination of these two trigrams gives rise to a specific hexagram. The hexagram conveys a unique set of circumstances, and energies, and can offer insight and guidance in a reading.

Here’s a more detailed explanation of the significance of the lower and upper trigrams:

The Lower Trigram:

• The lower trigram represents the internal or inner aspects of the situation or individual. It relates to the underlying influences, motivations, and attitudes that form the basis of the current situation.
• This trigram signifies the individual’s or situation’s inherent qualities, character, and starting point, offering insights into their fundamental nature and predispositions.
• In a reading, the lower trigram provides a context for understanding the roots or origins of the situation and offers guidance on how to approach it from within.

The Upper Trigram:

• The upper trigram signifies the external or outward manifestations of the situation or individual. It relates to the developing or unfolding aspects of the current circumstances.
• This trigram represents the changes, influences, and potential outcomes emerging or becoming visible in the situation.
• In a reading, the upper trigram offers insights into how the situation is evolving, the challenges and opportunities ahead, and how the individual or situation is interacting with the external environment.

The Building Blocks are Elements

In total, there are 8 trigrams that serve as the building blocks for the 64 hexagrams. Each trigram represents a specific natural element, energy, or concept. Here are the eight trigrams along with their names, meanings, and representations:

1. ☰ Qian (乾) – The Creative

The King Wen Sequence

The most famous ordering of hexagrams is the King Wen sequence, attributed to King Wen of the Zhou Dynasty. According to legend, King Wen is said to have received divine inspiration in his dreams, leading to the creation of the sequence. This sequence is the one that is used to arrange the hexagrams in the I Ching.

Complementary Pairs

The King Wen sequence is organized in complementary pairs of hexagrams. Each hexagram is followed by its mirroring partner, which has the same lines but is turned upside down. These complementary hexagrams reflect contrasting energies or situations. Some of the 64 hexagrams do not change when being turned upside down. In these instances, the partner is created by switching the lines; broken becomes unbroken, and yang becomes yin.

The Book of Changes – the movement of yin and yang

The partnering in I Ching, also called the Book of Changes, is logical and reflects the interplay between yin and yang. The King Wen sequence as a whole though, the arrangement of the pairs, appears illogical. The reason for its arrangement remains unknown. The I Ching system seems to be more akin to telling a story. It reminds me of tarot, which moves from the innocent Fool to the encompassing World. This story in the Book of Changes explores life phases, and can give an understanding of the movement, or patterns, of the universe.

The 64 Hexagrams Tell a Story

Each hexagram represents a unique stage or aspect of the cosmic journey. Here’s a summarized version of the story:

1. Hexagram 1 – The Creative (乾 qián): The story begins with “The Creative,” representing the birth of the universe and the primal force that initiated all existence.
2. Hexagram 2 – The Receptive (坤 kūn): Following the creative force, “The Receptive” embodies the receptive and nurturing aspect, like the Earth that welcomes and sustains life.
3. Hexagram 3 – Difficulty at the Beginning (屯 chún): The journey encounters challenges and obstacles, signifying the initial struggles of existence.
4. Hexagram 4 – Youthful Folly (蒙 méng): Representing youthful naivety and inexperience, where the journeyers are learning the rules of life.
5. Hexagram 5 – Waiting (需 xū): A time of patience and contemplation, akin to the elements waiting to evolve into something more complex.
6. Hexagram 6 – Conflict (訟 sòng): As complexity arises, conflicts and tensions emerge, symbolizing the dynamic interplay of elemental forces.
7. Hexagram 7 – The Army (師 shī): The elements organize themselves, forming an army of forces ready for action and transformation.
8. Hexagram 8 – Holding Together (比 bǐ): Elements come together, representing cohesion and unity, much like the early stages of matter formation.
9. Hexagram 9 – Small Accumulating (小畜 xiǎo chù): Growth and accumulation are observed, as the elements gather and build upon each other.

Fun Fact: Human Design goes old-school

When Human Design was created it used a hexagram system that predates I Ching -the circular Fuxi or Fu Hsi system. Since the King Wen sequence is the one that is established, Ra Uru Hu still numbered the hexagrams according to King Wen. This is why when you see the Rave Mandala, you see the Fuxi hexagrams layered on the zodiac. Because of its numbering, if you want information about a particular Human Design gate or a Gene keys key, you can still read up on the same hexagram number in your regular I Ching.
