仁王護國般若波羅蜜多經疏 3.186

3.186

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.
