俱舍論疏 12.75

12.75

論「由後一濁至及無病故」，明眾生濁故令智慧念等悉被衰損。《婆沙》一百十三云「有情衰損者，謂劫初時，此贍部州廣博嚴淨，多諸淳善福德有情，城邑次比，人民充滿。至劫末時，唯餘萬人。」准《婆沙》，衰損有情有二：一令劣惡、二令數少。惡是濁義，數少非濁義。如濁水、濁酒，不以少故名濁，但以居下滓穢名濁。此論明有情濁故，略不論少。

On the Śāstra's text, "Due to the last one turbidity... and freedom from disease": Explaining that because of the turbidity of sentient beings, wisdom, mindfulness, and so forth are all degraded. The Vibhāṣā, fascicle 113, says: "The degradation of sentient beings means that at the beginning of the kalpa, this continent of Jambudvīpa was vast, pure, and adorned, with many gentle, wholesome, and meritorious sentient beings, cities and towns contiguous, and people filling them. When it reaches the end of the kalpa, only ten thousand people remain." According to the Vibhāṣā, the degradation of sentient beings has two aspects: first, making them degraded and bad; second, making them few in number. Badness is the meaning of turbidity; fewness in number is not the meaning of turbidity. Just as with turbid water or turbid wine, they are not named turbid because of being little, but rather named turbid because of the sediment and defilement settling at the bottom. Since this treatise explains the turbidity of sentient beings, it omits discussing fewness.
