仁王護國般若波羅蜜多經疏 2.84

2.84

解曰：一切智智者，謂佛所有本後二智。不唯文字及以所詮并菩薩空，乃至佛果諸相永寂，亦復皆空。上來別解三般若中皆通因果，如文釋竟。大文第二總明般若。於中分三：一總標境智、二別釋境智、三總結皆如。且初第一總標境智。

Exposition: "The wisdom of all wisdoms" refers to the two cognitions, fundamental and subsequent, possessed by the Buddha. Not only are the letters and what they express, along with the bodhisattva, empty, but even the buddha-fruit, in which all marks are eternally quiescent, is also completely empty. Above, the separate explanation of the three kinds of prajñā has in each case encompassed cause and effect; the explanation of the text is finished. The second major section generally clarifies prajñā. This is divided into three: 1. generally indicating object and cognition; 2. separately explaining object and cognition; 3. generally concluding that all are suchness. First, the general indication of object and cognition.
