大般涅槃經義記 3.55

3.55

就明菩薩不須教中，文別有三：一人能降魔故不須教、二「阿竭陀」下法力滅邪故不須教。前中初喻，「學大」下合，「得聞」下釋。於中，初明智慧深明，聞經不怖，故不須教；「何以故」下，殖福久遠，於魔不畏，故不須教。後明法力滅邪之中，初先立喻，「人」喻菩薩，「藥」喻大乘，「不畏蛇」等明人不畏，「亦能消」下彰法能滅。合中，「大乘」合阿竭陀，「不畏魔」等合上不畏一切蛇等，「亦能降」下合上能消一切毒等。

Regarding the section explaining that the bodhisattva does not require instruction, in the text there are distinctly three [parts]: first, because the person is able to subdue Māra, he does not require instruction; second, from "agada" onward, because the power of the Dharma extinguishes heterodoxy, he does not require instruction. In the former, there is first an analogy; from "studies the Great" onward is the application; from "having heard" onward is the explanation. Therein, it first explains that with wisdom profoundly luminous, hearing the sūtra one is not terrified, hence not requiring instruction; from "Why is this?" onward, having planted blessings long ago, toward Māra one has no fear, hence not requiring instruction. In the subsequent [part] explaining that the power of the Dharma extinguishes heterodoxy, it first sets up an analogy: the "person" is an analogy for the bodhisattva; the "medicine" is an analogy for the Mahāyāna; "does not fear snakes," etc., clarifies that the person has no fear; from "is also able to eliminate" onward reveals that the Dharma can extinguish [heterodoxy]. In the application, "Mahāyāna" corresponds to the agada; "does not fear Māra," etc., corresponds above to not fearing all snakes, etc.; from "is also able to subdue" onward corresponds above to being able to eliminate all poisons, etc.
