無明有愛為種　二法門也。什曰。向總說。此開為二門也。一切結屬二故偏舉二門也。自下次第廣開。又解文云。無明性即是明。又云。不滅癡愛起於明脫。

"Ignorance and craving for existence are the lineage." The two dharma gates. [Kumāra]jīva says: "Previously it was spoken in general; here it opens into two gates. Because all fetters belong to these two, he specifically raises these two gates. From here on, he opens them broadly in sequence." Another interpretation says: "The nature of ignorance is itself illumination." It also says: "Without extinguishing delusion and craving, illumination and liberation arise."
