The Buddha's teaching of radical impermanence applies to all formations without exception, especially to the five aggregates of clinging, to our own personality. To the eye of insight our entire being dissloves into a compound of conditioned factors.

First take the aggregate of material form. The body is made up of minute groups of material phenomena which are themselves actually streams of events arising and passing away with incredible speed. The change takes so fast that the eye and the mind cannot register it. If we twirl a glowing stick in the dark, the eye fuses the moving points of light into the shape of a circle, so it appears to be a solid circle of light. In the same way all material form is fused together into the appearance of a solid body, but the solid body is only a mental representation and not a reality.
