1.276

是身如浮雲須臾變滅。是身如電念念不住　肇曰。變滅不住似釋無常。然皆取其虛偽不真。故速滅不住猶釋空義也。

"This body is like a floating cloud, changing and vanishing in an instant. This body is like lightning, not abiding from thought to thought." Sengzhao states: "Changing, vanishing, and not abiding seem to explain impermanence. However, all of these take its falsity and unreality as their point; thus, rapidly perishing and not abiding still explain the meaning of emptiness."
