仁王般若經疏 1.90

1.90

爾時佛告大眾者，將欲為說，所以聖命也。十六大國王意欲問護國土因緣者，王者本欲令七難不起、妖災消滅，境土清夷、萬民安樂，此王者本意。此則生下外護經文，即〈護國品〉也。吾今先為下，二明許說。夫欲衛其內外，先立其內行。內行若成，外護得備，所以先明內護也。護佛果者，即生此品護果經文。護十地行者，生下〈教化品〉護因經文。

"At that time the Buddha addressed the great assembly": intending to speak for them, he therefore gave the noble command. "The intention of the sixteen great kings is to inquire into the causes and conditions for protecting the state's territory": kings fundamentally desire that the seven difficulties do not arise, sinister calamities be extinguished, borders and lands be peaceful and tranquil, and the myriad people be at peace and happy; this is the kings' original intention. This then generates the text of the sūtra below on outer protection, which is the "Chapter on Protecting the State." From "I shall now first... for" downward is the second [part], clarifying his promise to speak. When one wishes to safeguard the inner and the outer, one must first establish the inner practice. If the inner practice is accomplished, outer protection can be fully equipped; therefore, inner protection is clarified first. "Protecting the Buddha-fruit" then gives rise to the sūtra text of this chapter on protecting the fruit. "Protecting the practice of the ten stages" gives rise to the sūtra text below in the "Chapter on Teaching and Transforming" on protecting the cause.
