5.341

若於過去，即可分別。如此如是，曾有相貌可分別故者，此釋頌中過去可分別能生雜染，非唯曾更而可非分別乃至生諸雜染者，此釋頌中分別曾所更非曾亦分別，此言意顯非唯過去曾所更境而可分別生諸雜染，現在諸境未曾更者未曾更故，雖不分明取其相貌，然隨過去曾得種類，此現新境亦可分別生諸雜染，結文可知。

Regarding "if it belongs to the past, it can indeed be conceptually constructed, because in this and that manner, characteristics that were once experienced can be conceptually constructed": this explains the statement in the verse that the past can be conceptually constructed and is able to give rise to defilement. Regarding "it is not only what has been previously experienced that can be conceptually constructed, up to giving rise to various defilements": this explains the verse's "one conceptually constructs what was previously experienced, and also conceptually constructs what was not previously experienced." The intention of this statement shows that it is not only past objects previously experienced that can be conceptually constructed to give rise to defilements; present objects that have not been previously experienced, precisely because they were not previously experienced, do not have their characteristics distinctly grasped, yet according with the classes previously attained in the past, these present new objects can also be conceptually constructed to give rise to defilements. The concluding text is self-evident.
