俱舍論記 6.235

6.235

「似自因法至遍行二因」者，釋第三句。定似自因名等流果。雖俱生、士用亦定似自因，有無間等士用與因不相似，故此等流非濫士用。雖遍行因亦取異部，為等流果染性同故，若士用果有性不同。

Regarding 'Dharmas resembling their own cause [...] the two causes that are all-pervading': Explaining the third line. That which definitely resembles its own cause is called the fruit of uniform outflow. Although co-arising and virile [fruits] also definitely resemble their own causes, there are immediately subsequent and other virile fruits that do not resemble their causes; therefore, this uniform outflow is not confounded with the virile. Although the all-pervading cause also takes different categories, it is a fruit of uniform outflow because its defiled nature is identical; whereas for the virile fruit, there are those whose natures differ.
