大乘法苑義林章 2.8

2.8

第四出體者，三藏體性義類不殊，總聊簡中已顯四體，且如護法四種體中相用別論。此即總以能說法者心上所顯，假實殊途聲名句文而為體性，隨其所應，三性、五法、蘊處界收。所引教理，廣如前說。

Fourth, concerning the presentation of the substantial nature: the intrinsic nature of the three piṭakas is not different in its conceptual category. In the general elucidation, four substantial natures have already been demonstrated; and just as in Dharmapāla's four kinds of substantial nature, their characteristics and functions are discussed separately. That is, they generally take the sounds, names, sentences, and phonemes—diverging into the conventional and the real—that are manifested on the mind of the teacher of the Dharma as their substantial nature; as appropriate, they are subsumed under the three natures, the five dharmas, and the aggregates, bases, and elements. The scriptural citations and rational arguments are extensive, as previously stated.
