俱舍論疏 6.12

6.12

The Śāstra says, “It should be known that when this arises... is an efficient cause,” which is the answer. Although knowledge obstructs the arising of defilements, and light obstructs seeing the stars, at the time when defilements arise, knowledge abides without obstructing, and at the time of seeing stars, light abides without obstructing; if they acted as obstructions, [the fruits] could not arise.
