菩薩瓔珞本業經 1.58

1.58

「佛子！五、善計量眾生力。所謂五陰：色者，異空色集，成大色分故，色相空。剎那剎那成心故，心相空；受想行識無集無散，一相無相故。

"Buddha-son! Fifth is skill in assessing the power of sentient beings, that is to say, the five aggregates: as for form, because form distinct from emptiness aggregates to form the great mass of form, the mark of form is empty; because the mind is formed moment by moment, the mark of mind is empty; feeling, conception, volition, and consciousness have no accumulation and no dispersion, because they are of a single signless mark.
