金光明最勝王經疏 6.151

6.151

捨身品，三門分別。言來意者，就學行流通中有五，第五成前諸品令學行意，有三，此即第三更重勸勉說此捨身。何以故？恐諸聞說行自利行當得成佛，猶不能習，故舉薩埵為利於他當捨身命，何不為自修行此經？故說捨身。故下經云「我為汝等說往昔利他緣，如是菩薩行成佛因當學」等。又恐聞說少行成佛，情生輕慢，故舉捨身，勸眾依學。故下經云「菩薩勝德相應慧勇猛精勤六度圓，常修不息為菩提入捨堅固心無倦」。前是正意，此是兼明，俱來意也。

Chapter on Relinquishing the Body: analyzed through three gates. Regarding the rationale for its introduction: within the circulation of learning and practice there are five [parts]. The fifth establishes the intention of having people learn and practice the preceding chapters, which has three parts; this is the third, providing an even stronger exhortation by speaking of this relinquishing of the body. Why so? Because it is feared that those who hear it taught that practicing self-benefiting practices will lead to attaining Buddhahood may still fail to train in it; therefore Mahāsattva is cited as having relinquished his bodily life for the benefit of others—why then would one not cultivate this sūtra for one's own benefit? Hence it speaks of relinquishing the body. Therefore the sūtra below says: "I have spoken for you of the past conditions of benefiting others; such bodhisattva conduct is the cause of achieving Buddhahood and should be learned," and so on. Furthermore, it is feared that hearing that minor practices achieve Buddhahood, one might give rise to slighting and arrogance; therefore it cites relinquishing the body to exhort the assembly to rely on it and learn. Hence the sūtra below says: "With wisdom corresponding to the bodhisattva's supreme virtues, vigorously and diligently perfecting the six perfections, constantly cultivating without cessation for the sake of bodhi, entering into relinquishment with a firm mind without fatigue." The former is the primary intention, and the latter is a concomitant clarification; both constitute the rationale for its introduction.
