唯識二十論述記 1.132

1.132

述曰：自下正解相續不定，如多餓鬼，同為惡業，同得惡果，多共一處聚集之時，同見膿河，相續不定，非於膿河，定唯一見，一不能見，如眩翳者，見髮、蠅等故，雖無實境，相續不定，其義亦成。外道、小乘、經部師等，皆信餓鬼同見膿河，故以為喻。量云：同於一時、同於此處，相續不定，其理得成。許無實境故，如餓鬼所見膿河。然頌膿河，更有「等」字，等何等法？

Commentary: Below is the direct explanation of the indetermination of continuum: as many hungry ghosts, having committed shared evil karma, receive shared bad results together, when they gather in large numbers in one place, they all together see a river of pus, which is indetermination of continuum; it is not that in regard to the river of pus, only one alone definitely sees it and another cannot see it, like someone with cataracts seeing hairs, flies, and so forth. Therefore, although there is no real object, indetermination of continuum is also established in meaning. The non-Buddhists, the Hīnayāna, the Sautrāntikas, and others all believe that hungry ghosts together see a river of pus, hence it is used as a simile. The inference says: "At the same time and in the same place, indetermination of continuum is established in principle; because it is accepted that there is no real object; like the river of pus seen by hungry ghosts." However, the verse's "rivers of pus" further has the word "and the like" (等); what things are included by "and the like"?
