Vibration
All things are in motion, from the subtle to the dense.
Nothing is at rest; every body, every field, every thought is in motion. What appears still is only a vibration beyond the measure of the senses. Differences of state are differences of rate, and the art of alteration is the art of changing vibration. This principle is the source of frequency, tone, and resonance. It explains why forms can shift, why moods can be transmuted, and why harmony brings coherence to a system. To understand vibration is to understand the language of energy and the means by which the invisible becomes the visible. In geometry, vibration is seen as rhythm within the line and pulse within the curve. That which moves together coheres; that which moves apart disperses.
