第二解制立中，景云：一、道理清淨者，諸佛制戒有深所以；二、果清淨者，依戒修行得沙門果；三、攝受清淨者，攝受行人；四、外清淨者，不招議謗；五、內清淨者，調伏諸根；六、具分清淨者，性戒遮戒皆悉具足。後四可解。

In the second [section], explaining the establishment [of precepts]: Jing says: First, purity of principle means that the Buddhas establish precepts with profound reasons. Second, purity of fruit means that relying on the precepts to cultivate practice, one attains the fruits of the recluse. Third, purity of inclusion means taking in practitioners. Fourth, external purity means not incurring criticism or slander. Fifth, internal purity means subduing the sense faculties. Sixth, purity in full measure means that both inherent precepts and prohibitive precepts are completely fulfilled. The latter four are easy to understand.
