大壯
Great Power — one of the sixty-four archetypal situations in the Book of Changes.
The Judgment
Great strength is present. It does best when it follows correct principles.
The Image
Thunder rolls across the sky, so the wise person does not step off the path of propriety.
How to use it
Use strength with propriety. Power without restraint backfires.
Structure
Six lines: 震 Thunder (Zhen) above and 乾 Heaven (Qian) below. Lines are read from the bottom up.
