法華玄論 5.158

5.158

次明五濁義。初序大意。所言明五濁者，為釋前三後一之義也。若言三世諸佛皆為一大事因緣出現於世者，何故不發軫即說一乘，而前說三乘後明一乘耶？為釋此疑，故云眾生五濁障，不堪聞一。是以先三後一，過在眾生，非佛咎也。為此義故，又明五濁也。晚見論云「為釋疑故來。有人疑佛何時說此種種方便法耶？是故釋云：為五濁惡世故說三乘。」此意正以劫濁為端，故偏言時耳。以惡世中即有惡眾生，乃至煩惱見等也。

Next, explaining the meaning of the five turbidities. First, an overview of the main idea. Explaining the five turbidities is to explain the meaning of the three [vehicles] first and the one [vehicle] later. If all the buddhas of the three periods appear in the world for the causes and conditions of the one great matter, why did they not preach the one vehicle from the very start, but instead preached the three vehicles first and clarified the one vehicle later? To resolve this doubt, it is stated that sentient beings are obstructed by the five turbidities and are unable to bear hearing the one. Therefore, [expounding] the three first and the one later is the fault of sentient beings, not the error of the Buddha. For this reason, the five turbidities are further explained. Later, looking at the treatise, it states: 'It comes in order to resolve doubts. Some doubt: at what time does the Buddha preach these various skillful means? Therefore it is explained: he preaches the three vehicles for the evil age of the five turbidities.' This meaning specifically takes the turbidity of the kalpa as the beginning, and therefore speaks specifically of time. For within an evil age there are evil sentient beings, and likewise afflictions, views, and so forth.
