大般涅槃經義記 8.60

8.60

The above has extensively explained [the practices]; from here below is the fourth [section], praising the capacity of their practice. Therein, it first explains that relying on the preceding five kinds, one can generate benefit for oneself; "like a father and mother..." and below explains that one can benefit others. Within the former, self-benefit, it first opens three gates: "doing what is difficult to do" is the practice of vigor; "enduring what is difficult to endure" is the practice of patience; "giving what is difficult to give" is the practice of generosity (dāna). Next it explains their marks, and finally clarifies freedom from attachment: "though able to do it, not thinking 'I do it'" is freedom from attachment regarding the first; "patience and giving are likewise" analogizes the latter two gates.
