大般涅槃經義記 6.74

6.74

就下別中，先問起發，昔時言得，今以何義道其不得？下對釋之，於中先明緣覺不得，後辯聲聞。就緣覺中，初總明其無四無礙，「何故默」下別明不得，「是故緣覺一切無」下總以結之。就初總中，「菩薩度生修四無礙」舉大顯小，「緣覺修寂，若化眾生，但現神通，默無所說，云何當有」辯小異大。別中，先明無辭無樂，「何故默然」徵前起後。下對釋之，於中先明緣覺之人不能說法令人得燸，乃至不能令人發於三菩提心，「何以」下釋，以無經故。「是故」下結，不能說故，無辭無樂。

In the specific part below, it first asks to raise the issue: in the past it was said that they attain them, so by what meaning is it now said that they do not attain them? Below, it responds and explains it: therein, it first clarifies that pratyekabuddhas do not attain them, and then explains śrāvakas. Concerning pratyekabuddhas, it first generally clarifies that they lack the four unobstructed knowledges; from "Why are they silent?" onward, it specifically clarifies their non-attainment; from "Therefore, pratyekabuddhas entirely lack [them]" onward, it summarizes and concludes it. In the first general part, "Bodhisattvas cultivate the four unobstructed knowledges to deliver sentient beings" cites the great to reveal the small; "Pratyekabuddhas cultivate quiescence; if they transform sentient beings, they merely manifest supernormal powers and remain silent without speaking; how could they possess them?" distinguishes the small to differentiate it from the great. In the specific part, it first clarifies the lack of phrasing and delightful discourse; "Why are they silent?" queries what preceded to initiate what follows. Below, it responds and explains it: therein, it first clarifies that pratyekabuddhas cannot preach the Dharma to cause people to attain the heat [stage], nor can they even cause people to bring forth the mind toward sambodhi; from "Why?" onward, it explains that it is because they have no scriptures. From "Therefore" onward, it concludes: because they cannot preach, they lack phrasing and delightful discourse.
