俱舍論記 7.85

7.85

Regarding "Derived matter for the great elements... because it is the fruit of the great elements": this explains the fourth line. Based on this verse text, the ten causes are called cause-and-condition. Therefore, the earlier question asked: how are the great elements and derived matter mutual cause-and-condition with respect to themselves and each other? This agrees with the Mahāvibhāṣā in constructing its argument on the basis of the ten causes.
