大般涅槃經義記 6.174

6.174

解調御中，先問、後釋。釋中初言「自既丈夫」以為一門，「復調丈夫」復為一門。「實非丈夫、非不丈夫，因調丈夫故名丈夫」顯上初門。「一切男」下顯向後門，於中，先明所化丈夫，後明如來能調之義。前中初言「若男、若女，若具四法則名丈夫」總以標舉，「何等」下列，「具足」下結。「若有男子無此四」下舉非顯是。就明如來能調之中，初先法說，次喻，後合。「御者調馬無有定」下明佛過世。

In explaining 'tamer' (puruṣadamyasārathi), there is first a question and then an explanation. In the explanation, first stating 'being himself a hero' constitutes one gate, and 'further taming heroes' constitutes another gate. 'Truly neither a hero nor not a hero, yet because he tames heroes he is called a hero' clarifies the first gate above. From 'all men' onward, it clarifies the latter gate. Within this, it first clarifies the heroes to be transformed, and next clarifies the meaning of the Tathāgata being able to tame them. In the former, first stating 'whether a man or a woman, if endowed with four dharmas they are called a hero' marks it out comprehensively; from 'what are they' onward, it lists them; from 'fully endowed' onward, it concludes. From 'if there is a man without these four' onward, it raises the negative to reveal the positive. In clarifying that the Tathāgata is able to tame, first is the Dharma exposition, next a simile, and then the application. From 'a charioteer taming a horse has no fixed [method]' onward, it clarifies that the Buddha surpasses the worldly.
