金光明最勝王經疏 5.5

5.5

解妨者，問，經云「觀察擁護此贍部洲，我等諸王名護世」者，能行之者通於三洲及欲色天，何故但唯觀勸此洲？答：就佛所住且言觀此，實通於餘。又餘三洲及欲色天，苦事既微厭慧不猛，惡趣雖苦無勝慧心。創能發心，必須厭深慧猛，是故偏說觀贍部洲。問：四天護境各有封疆，何故四王俱言護此？答：據世俗境各護一洲，敬法尊人同護於此。又所住境雖各一方，攝諸龍鬼通為護四。據護勝法，偏言觀此。問：此與後品俱四天王，二品何別？答：此品四王讚勸行經、發願護持；後品世尊讚美，令廣願護，故二品別。

As for resolving objections: Question: The sūtra states, "Observing and protecting this Jambudvīpa, we kings are named the Protectors of the World." Since practitioners are found across the three continents as well as the desire and form heavens, why do they observe and exhort only this continent? Answer: Regarding the place where the Buddha resides, it is provisionally said to observe this [continent], though in reality it extends to the rest. Furthermore, in the other three continents and the desire and form heavens, suffering is slight and weary aversion through wisdom is not intense; and though the miserable destinies are painful, they lack the mind of supreme wisdom. To generate the initial resolution, one must have deep weary aversion and intense wisdom; therefore, the text specifically speaks of observing Jambudvīpa. Question: The four heavens have their respective bounded territories to protect; why do all four kings say they protect this [continent]? Answer: In terms of the mundane realm, each protects one continent; but out of reverence for the Dharma and respect for persons, they unite in protecting this one. Moreover, although their dwelling realms each belong to a distinct quarter, their gathering of the nāgas and spirits universally protects all four. In terms of protecting the supreme Dharma, it specifically speaks of observing this [continent]. Question: This and the subsequent chapter both concern the Four Heavenly Kings; what is the difference between the two chapters? Answer: In this chapter, the Four Kings praise and encourage the practice of the sūtra and make vows to protect and uphold it; in the subsequent chapter, the World-Honoured One praises them and causes them to broaden their vows of protection. Hence the two chapters differ.
