瑜伽論記 21.38

21.38

又解：修四無量故，慧淨七者，一、釋一遠離；二、邊知三解脫，二知二自性；三、知三無性；四、知世俗五明外明內明聲明因明醫方明也；五、知勝義；六、無分別多所住；七、無量總法乃至法隨法行，泰云：又無分已下有二，前是止慧，後是觀慧，加行五慧名七種慧者，即同此判。一釋：若諸菩薩至是名為慧者，是總釋慧名。自下釋七相，下判亦同，今依前釋。

Another interpretation: because of cultivating the four immeasurables. The seven purities of wisdom: One interpretation: 1. detachment; 2. knowing the three deliverances at the extremes and knowing the two inherent natures; 3. knowing the three non-natures; 4. knowing the conventional five sciences: external sciences, internal science, linguistic science, logical science, and medical science; 5. knowing the ultimate truth; 6. frequently abiding in the non-conceptual; 7. the immeasurable totality of dharmas up to practicing Dharma in conformity with Dharma. Tai says: Furthermore, below 'non-conceptual' there are two: the former is calming wisdom, the latter is insight wisdom; the five wisdoms of application called the seven kinds of wisdom also conform to this classification. One interpretation: from 'if bodhisattvas…' to 'this is called wisdom' is the general explanation of the name of wisdom. What follows explains the seven marks; the lower classification is also the same. Here we follow the former explanation.
