24.56

第九解過，景師云：墮於生闇者，生上二界無明昏闇五支，還是觀諸行自性因緣，雜染清淨因緣，及以清淨。達師云：三種世界者，三界也。

Ninth, in explaining faults: Master Jing says: "Falling into the darkness of birth" refers to the five branches of ignorance and darkness of birth in the higher two realms, which are still observing the intrinsic nature, causes, and conditions of all conditioned phenomena, the causes and conditions of defilement and purification, and purification itself. Master Da says: "The three kinds of world" refers to the three realms.
