大乘法苑義林章 2.8

2.8

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.
