大方廣圓覺修多羅了義經略疏 2.1139

2.1139

四也。但諷前能治，以所治憎愛是犯戒因，云未解脫亦違戒德故。此云不犯及永淨也。

This is the fourth. It merely echoes the preceding antidote, because the love and hate to be cured are the causes for breaking precepts, and stating that they are 'not liberated' also runs contrary to the virtue of the precepts. Hence it states here 'not transgressing' and 'eternally pure.'
