21.112

「練根時者謂轉根時」者，釋第三章。《正理》云「說得果言既無差別，如攝四果應攝練根，以轉根時必得果故，何勞長說此練根言？為顯練根異斷惑得果故，得果外說練根無失。

Regarding "The time of refining the faculties refers to the time of transforming the faculties": this explains the third heading. The *Nyāyānusāra* says: "Since the statement 'obtaining the fruit' is without distinction, just as it encompasses the four fruits, it should also encompass refining the faculties, because when transforming the faculties one definitely obtains a fruit; why bother to state this 'refining the faculties' redundantly? In order to show that refining the faculties is distinct from severing defilements to obtain the fruit, there is no fault in stating the refining of the faculties separately from obtaining the fruit."
