俱舍論記 2.73

2.73

「入胎經中至差別義成」者，論主又別通。經唯說六界為士夫者，為顯此六初受生時體用強勝，能成士夫根本事故。以四大是造色所依，空是動所依，心是心所所依，所依勝故別說非唯爾所。廣如《瑜伽》五十六說。經雖說六觸，然更有餘心所法。經雖說六界，何妨有餘所造色。若言說六界即無餘造色，經亦說六觸，應無餘心所。亦不應執心所即心，經言想等依止心故。豈心自體還依自耶？又經亦說有貪心等。言觸處者，觸之所依故名觸處，即眼等六根。故《婆沙》七十四云「復次眼等六處，作觸所依義，名六觸處（已上論文）。」此中引意，取能依觸，非所依處。

On the passage "In the Garbhāvakrānti-sūtra [...] the differentiated meaning is established": The author of the śāstra provides an additional distinct harmonization. The sūtra speaks only of the six dhātus as making up a person in order to make evident that when first taking birth, the substance and function of these six are prominent and strong, able to accomplish the fundamental affairs of a person. Because the four great elements are the support of derived matter, space is the support of movement, and mind is the support of mental factors—it is because the supports are preeminent that they are spoken of separately, not that these are all there is. It is explained in detail as in chapter fifty-six of the Yogācārabhūmi. Although the sūtra speaks of six contacts, there are yet other mental factors. Although the sūtra speaks of six dhātus, what prevents there being other derived matter? If one asserts that stating six dhātus means there is no other derived matter, then since the sūtra also states six contacts, there should be no other mental factors. Nor should one hold that mental factors are identical with the mind, for the sūtra says that ideation and the like rely on the mind. How could the mind's own nature rely upon itself? Furthermore, the sūtra also speaks of a mind with lust and the like. As for the expression "bases of contact" (sparśāyatana): because they are that upon which contact relies, they are called bases of contact, which are the six faculties of the eye and the rest. Therefore the Mahāvibhāṣā, fascicle seventy-four, says: "Furthermore, the six āyatanas of the eye and the rest, in the sense of serving as the basis for contact, are called the six bases of contact" (end of śāstra passage). The intention in citing this here is to take the supported contact, not the supporting bases.
