大般涅槃經義記 4.96

4.96

明不解中，初明隨逐半字之義，後明隨逐無字之義。隨半字中，生煩惱者為半字故，有人隨之不能解了如來之性；又詮世諦為半字故，有人隨之不能解知如來之性；又詮小乘為半字故，有人隨之不能解知如來之性。隨無字中，先問、次辨。辨中，初明隨逐惡法無有善字，「又無字」下明隨小法不知大乘名隨無字，「我今已說隨逐無字」總以結之。

Within clarifying non-understanding, it first clarifies the meaning of following the half letters, and subsequently clarifies the meaning of following non-letters. Within following the half letters, because that which gives rise to afflictions constitutes the half letters, there are those who follow them and cannot understand the nature of the Tathāgata; also, because expressing conventional truth constitutes the half letters, there are those who follow them and cannot understand the nature of the Tathāgata; also, because expressing the Hīnayāna constitutes the half letters, there are those who follow them and cannot understand the nature of the Tathāgata. Within following non-letters, it first asks and next explains. In the explanation, it first clarifies that following bad dharmas has no good letters; from "Moreover, non-letters" onward, it clarifies that following lesser teachings without knowing the Mahāyāna is called following non-letters; "I have now spoken of following non-letters" brings it together in conclusion.
