俱舍論記 6.253

6.253

「約有所緣至准例應說」者，前明無所緣，今明有所緣。有所緣言，顯心、心所。剎那差別，顯前、後念。三性四句，思之可知。

"Regarding those having an intentional object, up to: 'should be stated by analogy'": previously, those without an intentional object were clarified; now, those with an intentional object are clarified. The words "having an intentional object" indicate minds (citta) and mental factors (caitta). The distinction between moments indicates the preceding and subsequent mind-moments. The four alternatives across the three natures can be understood upon reflection.
