What is Hexagram 34, Great Power?

Hexagram 34, Great Power (大壯 Dà Zhuàng), is built from Thunder (震 Zhèn) over Heaven (乾 Qián), and the Wilhelm-Baynes translation reads its themes as power, strength, ethics. The classical sources describe it as a pattern in the Book of Changes (易經 Yìjīng), a situation to recognise, not a verdict to obey.

Key Takeaways

  • Hexagram 34 is built from Thunder (震 Zhèn) over Heaven (乾 Qián).
  • Its central themes, power, strength, ethics, restraint, sit in the Wilhelm-Baynes lineage.
  • The classical pairing matches the hexagram to Tiger's Eye as the meditation stone.
  • Read alongside BaZi, Kua, and Compass School sector mapping for a fuller picture.
  • This is a pattern, not a verdict, the I-Ching frames reflection, not prediction.

The Judgment

The Power of the Great. Perseverance furthers.
The image

The Image

Thunder in heaven above: the image of the Power of the Great. Thus the superior person does not tread upon paths that do not accord with established order.

Master Wei Lin's Interpretation

Interpretation by Master Wei Lin, Chinese Metaphysics Scholar, pattern recognition, not fortune-telling

Thunder above heaven, immense power surging forward. You have real strength in your situation, but the I-Ching warns: power without ethics is just force, and force without wisdom gets its horns tangled in the hedge. Use your strength, yes, but along righteous paths only. What would it look like to be powerful and also correct?

The moving lines

The Six Lines

When a changing line appears in your reading, its text carries special guidance for your situation.

Line 1 (bottom)

Power in the toes. Continuing brings misfortune. This is certainly true.

Line 2

Perseverance brings good fortune.

Line 3

The inferior person works through power. The superior person does not act so. To continue is dangerous. A goat butts against a hedge and gets its horns entangled.

Line 4

Perseverance brings good fortune. Remorse disappears. The hedge opens; there is no entanglement. Power depends upon the axle of a big cart.

Line 5

Loses the goat with ease. No remorse.

Line 6 (top)

A goat butts against a hedge. It cannot go backward, it cannot go forward. Nothing serves to further. If one notes the difficulty, this brings good fortune.
