瑜伽論記 1.584

1.584

第六文中，堅攝云何？謂彼種子者，因隨果攝名為堅攝，又堅者則彼界，是實地體。堅攝者、謂髮毛等者，則是似地，果是因類故言堅攝。非執受種子者，謂無漏種子雖依於識識不緣，故名非執受。

In the sixth passage, [to the question] 'How is firmness included? That is, its seeds': the cause is subsumed under the fruit, so it is called 'firmness included'. Furthermore, firmness is that element itself, the real substance of earth. Regarding 'Firmness included refers to hair and the like': these are simulated earth; the fruit is of the same category as the cause, hence it is called 'firmness included'. 'Seeds that are not appropriated' refers to taintless seeds; although they rely on consciousness, consciousness does not take them as an cognitive object, hence they are called 'not appropriated'.
