瑜伽師地論略纂 7.3

7.3

「自性清淨」者，明思慧體，簡生得善，故名清淨。　「思擇所知」者，思擇一切所應知法。　「思擇諸法」者，思擇佛經長行及頌諸要法義。　「遠離一切不思議處」者，謂置記境及非己分諸地證境。　「能善了知黑說、大說」者，外道邪說及諸惡說，名黑說；內道正說及諸善說，名大說。　「於法少分，唯生信解」等者，謂非己分少所知解處，名法少分，但名信解，不應謗故。若於己分少所知法，應慧觀察。

Regarding "innately pure": this clarifies the substance of prajñā arisen from reflection; it excludes innate goodness, and is therefore called "pure." "Reflecting upon the knowable": reflecting upon all phenomena that ought to be known. "Reflecting upon the teachings (dharmas)": reflecting upon the essential doctrinal meanings of the Buddha's sūtras in prose and verse. "Distancing oneself completely from all inconceivable domains": this refers to the unanswerable points (avyākṛtavastu) and the domains realized in the various stages that are not within one's own sphere. "Being able to properly understand dark teachings and great teachings": the heterodox doctrines of non-Buddhists and various evil teachings are called "dark teachings"; the correct doctrines of the Buddhist teaching and various good teachings are called "great teachings." Regarding "generating only faith and understanding toward a fraction of the Dharma," and so forth: this means that toward points that are not in one's own sphere and of which one has little understanding, it is called a fraction of the Dharma; one should merely have faith and understanding, for one must not slander them. If it is a teaching of which one has some understanding within one's own sphere, one should investigate it with wisdom.
