維摩經略疏 10.13

10.13

問：三乘各有觀法，亦各有戒不？答：戒是和眾。若復別立支佛之戒，即是二戒二眾，不名為和，故戒不別立。三乘是觀法所習不同，故須分別。菩薩在俗非僧數攝，故別開戒。二乘若為白衣，不入僧，名為支佛。一世無二佛，不許別眾同聲聞眾，眾既同不開戒（云云）。

Question: If each of the three vehicles has its own contemplation method, do they also each have their own precepts? Answer: Precepts are for harmonising the assembly. If distinct precepts for pratyekabuddhas were additionally established, there would be two sets of precepts and two assemblies, which could not be called harmonious; hence precepts are not established separately. The three vehicles differ in the contemplation methods practiced, so they must be differentiated. Bodhisattvas abide in the secular life and are not subsumed within the count of the saṅgha; hence separate precepts are opened for them. If beings of the two vehicles become white-robed laity, they do not enter the saṅgha and are called pratyekabuddhas. In one world there are not two buddhas; they are not permitted to form a separate assembly and must share the assembly with śrāvakas. Since the assembly is identical, separate precepts are not opened (and so forth).
