The Lines

The I Ching Foundation of Human Design Lines

The Six Lines of the Hexagram

The ancient I Ching contains 64 hexagrams. A hexagram is a composition of six horizontal lines in a stack.  In Human Design, the Human Design mandala, the circle surrounding your Body Graph, contains the 64 gates. If we think of the Human Design gates as the numbers on a clock, the lines become the hands of that clock.

Structure and Meaning

According to the Human Design Academy by Ra Uru Hu, each hexagram consists of 6 lines (from which it derives its name since hex means 6). The hexagram is built from the bottom up so the first row refers to the bottom row, and the top row refers to the sixth row.

Yin and Yang in the Lines

The hexagrams contain the same binary structure as the yin-yang expression. In the context of human design, yin is receptive and yang is creative. The first, third and fifth lines are accepted. And the second, fourth and sixth lines are creative.

The Trigram Structure

The hexagram is made up of six lines, broken (yin), or solid (yang). These lines are always read from the bottom to the top, and they’re separated into what we call trigrams, with the bottom three lines forming the lower trigram, and the top three forming the upper trigram. The lower trigram being related to intrapersonal energy themes experienced by the self, and the upper being concerned with transpersonal energy themes, experienced in the context of relationships with other people.

The Eight Trigrams and Their Elements

According to the I Ching tradition, there are 8 elements: fire, earth, lake, heaven, water, mountain, thunder, and wind. These trigrams can be seen as the building blocks for all the energies and expression of life.

The eight trigrams and their associations are:

1. ☰ Qian (Heaven) – Pure yang energy, creativity, strength
2. ☷ Kun (Earth) – Pure yin energy, receptivity, nurturing
3. ☳ Zhen (Thunder) – Movement, arousal, initiative
4. ☴ Xun (Wind) – Gentle penetration, flexibility
5. ☵ Kan (Water) – Depth, danger, the abyss
6. ☲ Li (Fire) – Clarity, illumination, clinging
7. ☶ Gen (Mountain) – Stillness, stopping, meditation
8. ☱ Dui (Lake) – Joy, satisfaction, exchange

The House Metaphor

If you think of the hexagram as a two-storey house, it will help you to visualise the structure and importance of each line. The ground floor is the lower trigram, and the upstairs is the upper trigram. The first line of the hexagram forms its foundation and relates to introspection.

The Mathematical Connection to DNA

The mathematical structure of the I Ching hexagrams has exact similarities to DNA. The I Ching is made up of 2 lines – yin and yang – grouped in particular ways to create 4 bigrams, 8 trigrams and 64 hexagrams. DNA is also made up of 64 paired triplets called codons. 

When Lines Are Missing

Reference: The Taoist I Ching

The absence of certain lines in your design isn’t a deficiency—it’s a different kind of gift. When you lack certain line energies, you:

1. Gain Freedom: You’re not bound by that line’s particular pressures or patterns
2. Find Alternative Paths: Your creativity flows through the lines you do have
3. Attract Complements: You naturally draw people who embody your missing lines
4. Develop Uniqueness: Your creative expression becomes distinctly yours

Consider the artist with no Line 1s who creates intuitive, immediate work without needing theoretical foundation. Or the musician with no Line 4s who composes for humanity rather than their personal network. These aren’t limitations—they’re liberations.

When Lines Dominate

When you have many of one line (like 8 Line 3s or 10 Line 1s), that energy becomes a dominant theme in your creative life:

1. Amplified Gifts: The strengths of that line become superpowers
2. Intensified Challenges: The struggles also magnify
3. Clear Direction: Your creative path becomes more defined
4. Deeper Mastery: You embody that line’s wisdom profoundly

The key is recognizing this dominance and working with it rather than against it. If you have many Line 3s, embrace experimentation as your primary creative mode. With many Line 1s, honor your need for deep research.

Conclusion: Your Unique Creative Signature

Your lines aren’t limitations—they’re your unique creative signature. Whether you alter form through:

• Principles (Line 1)
• Planning and Ritual (Line 2)
• Rejection and Sensitivity (Line 3)
• Patient Influence (Line 4)
• Practicality or its Absence (Line 5)
• Sensitivity or Detachment (Line 6)

Remember: Creation isn’t just what you do—it’s who you are. Every moment, with every choice, you’re altering form, contributing to the universe’s endless creative expansion. The question isn’t whether you’re creative, but how your unique design expresses the creativity that you are.
