俱舍論記 29.128

29.128

「經說執我至不能清淨」者，論主又引第十三經顯我無有。經說：執我有五種失，一謂起我見、二有情見、三墮惡見趣、四同諸外道、五越路而行。於空性中心不悟入，釋起我見。不能淨信，釋有情見。不能安住，釋墮惡見趣。不得解脫，釋同諸外道。聖法於彼不能清淨，釋越路而行。又解：言五失者，一謂起我見及有情見墮惡趣；二同諸外道執我；三越正路而行；四於空性中心不悟入，不能淨信三寶、不能安住四諦、不得解脫涅槃；五聖法於彼執我身中，由惑覆障不能清淨。

Regarding "The sūtra states that clinging to a self ... cannot be purified": the author of the treatise cites a thirteenth sūtra to show that the self does not exist. The sūtra states: clinging to a self has five kinds of faults: first, giving rise to the view of a self; second, the view of a sentient being; third, falling into the destiny of bad views; fourth, being identical with the non-Buddhists; fifth, departing from the path. Failing to enter into emptiness in mind explains giving rise to the view of a self. Inability to have pure faith explains the view of a sentient being. Inability to abide explains falling into the destiny of bad views. Inability to attain liberation explains being identical with the non-Buddhists. The noble Dharma being unable to be purified in him explains departing from the path. Another explanation is: as for the five faults: first, giving rise to the view of a self and the view of a sentient being and falling into bad destinies; second, being identical with the non-Buddhists who cling to a self; third, departing from the correct path; fourth, failing to enter into emptiness in mind, being unable to have pure faith in the Three Jewels, being unable to abide in the Four Noble Truths, and failing to attain liberation and nirvāṇa; fifth, the noble Dharma, within the person who clings to a self, cannot become purified because it is covered and obstructed by defilements.
