仁王護國般若波羅蜜多經疏 3.186

3.186

解曰：言云何者，正是問辭。諸善男子者，脩行人也。於此經中者，即此經也。所覩雖多，般若同故。言明了者，於諸理事皆明了也，或於理明、於事了故。言覺解者，覺謂現證、解謂悟解，於理明證、於事了解，是故名為明了覺解，此自利也。為人演說者，即利他也。從此第二如來正答。大分為二：初明十三法師奉持、後明十六國王奉持。就明法師中，文分為二：一略明法師、二廣明行位。初明法師，文復分三：且初第一誡命諦聽。

Explanation: The words “how should” are the phrasing of the question. “Good sons” refers to practitioners. “In this sūtra” refers to this very sūtra. Although what was beheld was manifold, the prajñā is identical. “Clearly” means being clear regarding all principles and phenomena, or being clear regarding principle and understanding phenomena. “Understand and realize”: “realize” means direct realization; “understand” means awakening comprehension; clearly realizing principle and understanding phenomena is therefore called “clearly understanding and realizing,” which is benefiting oneself. “Expound it for others” is benefiting others. Next, the second: the Tathāgata's correct answer. It is broadly divided into two: first, clarifying the upholding by the thirteen Dharma masters; second, clarifying the upholding by the sixteen kings. Under clarifying the Dharma masters, the text is divided into two: first, briefly clarifying the Dharma masters; second, extensively clarifying their practices and stages. First, clarifying the Dharma masters is further divided into three parts: first, admonishing and enjoining them to listen attentively.
