首楞嚴義疏注經 1.640

1.640

「又如新霽，清陽昇天，光入隙中，發明空中諸有塵相。塵質搖動，虛空寂然。如是思惟，澄寂名空，搖動名塵，以搖動者名為塵義。」佛言：「如是。」

"Again, as when skies clear after rain and the pure sun rises into the sky, its light entering through a chink and illuminating the marks of various dusts in the air: the particles of dust drift and flutter, while empty space is completely still. Contemplating like this: clear stillness is called 'space', and drifting motion is called 'dust'; thus, drifting motion is the meaning of 'dust.'" The Buddha said: "So it is."
