1.522

即聞空中聲。曰。阿難如居士言。但為佛出五濁惡世現行斯法度脫眾生　二空聲舉應顯真疾身應物也。無為本真也。肇曰。以其愧惑故空聲正之如居士言。何有無漏之體嬰世之患。但為疾五濁群生故現斯疾。取乳勿慚也。五濁者劫濁眾生濁煩惱濁見濁命濁。

"Then I heard a voice in the air saying: 'Ānanda, it is as the householder says. It is only because the Buddha has appeared in the evil world of the five turbidities that he manifests the practice of this dharma to cross over sentient beings.'" Second, the voice in the air raises the responsive to reveal the real: the ill body responds to beings; the unconditioned is the fundamental real. Sengzhao says: "Because of his shame and bewilderment, the voice in the air corrected him: 'It is as the householder says. How could an outflow-free substance be afflicted with worldly troubles? But for the sake of the ill beings of the five turbidities, he manifests this illness. Go fetch the milk without shame.' The five turbidities are the turbidity of the kalpa, turbidity of sentient beings, turbidity of afflictions, turbidity of views, and turbidity of lifespan."
