俱舍論記 8.136

8.136

三「趣少分至皆化生故」者，釋。《正理》兩說。一說同此論。又一說云：有說濕生，現見多故。設有肉等聚廣無邊，下越三輪、上過五淨，容遍其量頓變為虫，是故濕生多餘三種。然無評家。

"Because small portions of the three realms [...] are all apparitionally born": explanation. The *Nyāyānusāra* gives two explanations. One is the same as this treatise. The second says: Some say moisture-born beings [are the most numerous], because they are visibly seen to be manifold. If there were a heap of meat or the like of boundless extent, reaching below past the three wheels and above surpassing the five Pure Abodes, insects could appear throughout its entire extent all at once; therefore moisture-born beings are more numerous than the other three modes. However, there is no evaluative judgment.
