俱舍論頌疏論本 1.38

1.38

拔眾生出生死泥者，嘆利他德也。一切眾生於生死泥淪沒無救，世尊哀愍，隨授所應正法教手，拔濟令出。此是恩德，大悲為體。言眾生者，有眾多生死故也。言泥者，有漏業煩惱異熟果為體。煩惱如水，業異熟如土，由此相參，成生死泥。

'Who pulls sentient beings out from the mire of saṃsāra' praises the virtue of benefiting others. All sentient beings are submerged in the mire of saṃsāra without rescue; the World-Honoured One takes pity, reaches out the hand of the appropriate true Dharma teachings according to their capacities, and pulls them out to save them. This is the virtue of benevolence, having great compassion as its essence. As for 'sentient beings' (sattva), it is because they undergo manifold births and deaths. As for 'mire', it has the vipāka-fruit of contaminated karma and afflictions as its essence. Afflictions are like water, and karma-vipāka is like earth; through their mingling together, they become the mire of saṃsāra.
