妙法蓮華經玄義 3.149

3.149

增三數明行者，謂戒、定、慧，此三是出世梯隥，佛法軌儀。《戒經》云：「諸惡莫作，諸善奉行，自淨其意，是諸佛教。」諸惡即七支過罪輕重非違，《五部律》廣明其相。如是等惡，戒所防止。諸善者，善三業，若散若靜、前後方便、支林功德，悉是清升，故稱為善。自淨其意者，即是破諸邪倒，了知世間、出世間因果，正助法門，能消除心垢，淨諸瑕穢，豈過於慧？佛法曠海，此三攝盡。

Regarding explaining practice by increasing to the number three, this refers to morality, concentration, and wisdom; these three are the ladder for transcending the world and the standard decorum of the Buddhadharma. The *Precept Sūtra* says: 'Refrain from all evil, / Practice all good, / Purify one's own mind: / This is the teaching of all buddhas.' All evil refers to the greater and lesser faults and violations of the seven categories of action, the marks of which are widely clarified in the *Vinaya in Five Divisions*. Such evils are prevented and stopped by morality. All good refers to the wholesome actions of the three karmas, whether distracted or tranquil, the preparatory and subsequent expedients, and the merits of the limbs and branches; all are pure and elevating, and are therefore called good. Purifying one's own mind means destroying all erroneous inversions, clearly understanding mundane and supramundane causes and effects, and the primary and auxiliary approaches to the Dharma; being able to eliminate mental defilements and cleanse all blemishes and impurities, what could surpass wisdom? In the vast ocean of the Buddhadharma, these three completely subsume all.
