俱舍論記 26.73

26.73

「此據作意至故無有失」者，經部師釋。此據作意，將入定時欲修覺支名修，非現前修無漏覺支，故無有失。

Regarding [the text from] “This refers to mental engagement” up to “there is no fault”: this is the Sautrāntika master's explanation. This refers to mental engagement; when about to enter absorption, the wish to cultivate the limbs of awakening is called 'cultivation'; it does not mean cultivating the undefiled limbs of awakening directly in the present [distracted state], so there is no fault.
