8.477

述曰：四、獨雜分別門，無明、愛、取三支說名獨相，獨者此體為支，不與餘支相交雜故。取中雖愛增上，非轉愛為增上貪故，又別有法故，餘是雜相，謂行及識等五轉，名有及生等故，即有、生等亦名為雜，體無異故，用他成故，第十但云：「三是獨相，行等是雜相」。

The Commentary states: Fourth, the category distinguishing unique and mixed marks. The three links of ignorance, craving, and grasping are called 'unique marks.' 'Unique' means that their own substance constitutes the link, without being intermingled with other links. Although in grasping there is the intensification of craving, it is not that craving transforms into intensified greed, and moreover there are other factors. 'The rest are mixed marks' means that formations and the five of consciousness, etc., are transformed and named existence, birth, and so on; thus existence, birth, etc., are also named 'mixed,' because their substance is not distinct, being constituted by relying on others. Fascicle 10 merely says: 'Three are unique marks, and formations, etc., are mixed marks.'
