俱舍論疏 29.133

29.133

論「若謂木等至無理能遮」，即薪是火難。既薪即是火，依義謂何？即所喻法定應是一，無理能遮。

On the Śāstra's statement: "If you say that wood and the like […] no reason can prevent it": This is the challenge that fuel is fire. Since fuel is fire, what does the meaning of 'dependence' mean? Then the phenomenon illustrated by the simile must definitely be identical, and no reason can prevent it.
