注維摩詰經 3.341

3.341

什曰：劫濁、眾生濁、煩惱濁、見濁、命濁。多歲數名由泓，多由泓名為劫。大劫如賢劫比也。大劫中有小劫，多諸惡事，總名劫濁。善人既盡、淳惡眾生，眾生濁也。除邪見已，諸煩惱如三毒等增上重者不以道理，能障聖道必入惡趣，如是結使煩惱濁也。除四見已，唯取邪見，謗無因果、罪福，及聖道、涅槃，是名見濁也。大劫初時人壽無量，爾時佛未出世。後受命漸短人壽六萬歲，爾時拘留孫佛出世。乃至百二十歲時，釋迦牟尼佛出現于世。自後漸短，乃至人壽三歲。百二十歲已下，盡名命濁也。彌勒生時，小劫更始，人壽更長也。

[Kumāra]jīva says: "[The five turbidities are] the turbidity of the kalpa, the turbidity of sentient beings, the turbidity of afflictions, the turbidity of views, and the turbidity of lifespan. A large number of years is called a yojana-equivalent, and many of these make a kalpa. A great kalpa is like the Bhadrakalpa. Within a great kalpa there are small kalpas filled with many evil events, collectively called the turbidity of the kalpa. When good people are exhausted and purely evil beings remain, that is the turbidity of sentient beings. Aside from wrong views, when various afflictions such as the three poisons become extremely severe contrary to reason, capable of obstructing the noble path and inevitably leading to evil destinies, such fetters are the turbidity of afflictions. Setting aside the other four views, when one adopts solely wrong views—slandering that there is no cause and effect, no sin and blessing, nor noble path and nirvāṇa—this is called the turbidity of views. At the beginning of a great kalpa, human lifespan is immeasurable; at that time no buddha appears in the world. Later, lifespans gradually decrease, and when human lifespan is sixty thousand years, Krakucchanda Buddha appears in the world. Down to when it is one hundred and twenty years, Śākyamuni Buddha appears in the world. From then on it gradually decreases down to a human lifespan of three years. A lifespan of one hundred and twenty years or less is collectively called the turbidity of lifespan. When Maitreya is born, the small kalpa begins anew, and human lifespan will be longer again."
