Origin

This character pictures a measuring scale or balance beam. The two instances of 行 (which sounds like "kou") frame the character and provide a sound hint for its pronunciation, while the central component represents the object being measured or weighed. The overall shape suggests a horizontal beam with supports on both sides, which is exactly what you'd need to check if things are in equilibrium. Over time, the visual image of a balanced measuring device became the word for equilibrium and the concept of balance itself.
