瑜伽師地論略纂 15.24

15.24

釋《六界經》云「唯欲顯說色、動、心所最勝所依」者，六界中，四大色所依，空是動往來所依，識是心所所依，唯識所依。若言六界無心所，心所無別體；六界不說於造色，色於無體？「乳、酪、生蘇三譬喻」者，法師云：經云經中說此三，譬喻離此三外是無喻也。六界外豈無餘心所也。備師云：此喻喻羯剌藍等初三位。太師云：乳喻欲界四大為我，酪喻色界有色應生，生蘇喻無色界空想生。轉增勝故，所以三喻。然豈三外色界等無心等耶？

Explaining the *Ṣaḍdhātu-sūtra*, it says: 'It only intends to explain the supreme bases of form, motion, and mental factors.' Among the six elements, the four great elements are the basis of form, space is the basis of movement and locomotion, and consciousness is the basis of mental factors; it is the basis only of consciousness. If it is said that because there are no mental factors in the six elements, mental factors have no separate substance, then since the six elements do not speak of derivative form, would form have no substance? Regarding the 'three analogies of milk, curd, and fresh butter': Master [Xuanzang] said, 'The sūtra says that in the sūtra these three are stated; the analogy means that outside of these three there is no analogy.' Outside the six elements, could there be no other mental factors? Master Bei said, 'This analogy illustrates the first three states, such as the kalala.' Master Tai said, 'Milk illustrates the four great elements of the desire realm as the self; curd illustrates the form realm where there is form that should arise; fresh butter illustrates the formless realm where the conception of space arises. Because they become progressively superior, these three analogies are used. Yet outside these three, how could the form realm and so forth lack mind, etc.?'
