大方廣圓覺修多羅了義經略疏 1.128

1.128

一、隨相門。復有二種：一、聲名句文體，體用假實相資故。故《十地經》有空中風（喻聲）畫（名等）之喻。二、通攝所詮體。若不詮義，文非教故。

1. The gate of conforming to characteristics. Furthermore, there are two kinds: 1. The essence of sounds, names, sentences, and words, because essence and function, provisional and real, assist each other; therefore, the Daśabhūmika-sūtra contains the simile of the wind (a simile for sound) drawing pictures (names, and so forth) in the sky. 2. Thoroughly encompassing the essence of what is expressed; for if they did not express meaning, the words would not be a teaching.
