大般涅槃經義記 7.268

7.268

第三德中，初問，次辯，後總結之。辯中，宣說慈無量心以為德體，四無量心皆是此德，且就初舉。又復諸行有分相門、有攝相門，若據分別，四行各別；若據攝相，舉一為首，餘皆入中。今就攝相，故舉一慈，統收餘三。文中初言「捨慈得慈，得慈不從緣」略以標舉，謂捨一切攀緣之慈，得彼平等無緣大慈，此無緣慈證實以成，據實反望由來無緣知從何生，故說得時不從因緣。

Regarding the third virtue, there are first a question, next an explanation, and then an overall conclusion. In the explanation, it proclaims the immeasurable mind of benevolence to be the essence of the virtue; all four immeasurable minds are this virtue, and [the text] merely raises the first one. Furthermore, practices have an analytical aspect and an inclusive aspect: if based on differentiation, the four practices are each distinct; if based on inclusion, one is raised as the head and the remainder all enter into it. Here, relying on inclusion, it therefore raises benevolence alone to comprehensively gather the remaining three. In the text, the initial statement, "abandoning benevolence, one attains benevolence; attaining benevolence does not come from conditions," briefly marks it out: it means abandoning all benevolence of grasping conditions and attaining that equal great benevolence without conditions. This unconditional benevolence is accomplished by witnessing the real; looking back based on the real, it has always been without conditions—how could one know from where it arises? Therefore it says that when attained, it does not come from causes and conditions.
