俱舍論記 18.61

18.61

「感第一有至說世善言」者，釋下兩句。有頂善思感最大果，約異熟果故說此言。若五果中據離繫果，則金剛喻定相應思能得大果，故諸結永斷為此思果故。雖諸無漏無間道思皆得離繫，非如此故。為簡此無漏思，故說世善言。

Regarding the passage from "Inducing the highest existence" up to "the words 'worldly wholesome' are spoken": this explains the latter two lines. Wholesome volition at the Peak of Existence induces the greatest fruit; this is spoken with respect to the fruit of ripening. If, among the five fruits, one considers the fruit of disjunction, then the volition associated with the vajropamasamādhi can attain the greatest fruit, because the permanent severance of all fetters is the fruit of this volition. Although all volitions of the unhindered paths that are uncontaminated attain disjunction, they are not like this one. In order to exclude this uncontaminated volition, the words "worldly wholesome" are spoken.
