俱舍論記 14.120

14.120

「論曰至四能學滿分」者，釋上兩句。經部難言：若諸近事皆具律儀，何緣世尊於五戒中言有四種鄔婆索迦：一能學一分，謂學一戒；二能學少分，謂學二戒；三能學多分，謂學三戒、四戒；四能學滿分，謂學五戒。

"The treatise states: ... fourth, one capable of training in the full portion" explains the upper two lines. The Sautrāntika objects, saying: If all upāsakas possess the complete discipline, for what reason did the World-Honoured One state that among the five precepts there are four kinds of upāsakas: first, one capable of training in one portion, meaning training in one precept; second, one capable of training in a lesser portion, meaning training in two precepts; third, one capable of training in a greater portion, meaning training in three or four precepts; fourth, one capable of training in the full portion, meaning training in five precepts?
