瑜伽論記 4.334

4.334

初文有十句，利益、安樂，一切無量所顯示者，四無量中皆有二故。四十四言：初三安樂後一利益者，彼說初三與世間現益名安樂，後一與出世後益名利益，故二差別。此依四種俱能拔苦與樂竝通能與智福小大果故俱名利樂，無怨、無敵、無惱害，意語身業，如次配之。如四大河眾流雜處者，喻四無量眾善所集。

The first text has ten phrases. Regarding "benefit and well-being are what are revealed by all immeasurables": because within all four immeasurables both exist. Fascicle forty-four states: "The first three are well-being and the last one is benefit." That text says that the first three bestow present worldly benefit, termed well-being, while the last one bestows subsequent supramundane benefit, termed benefit; hence the two are distinguished. Here, it relies on the fact that all four can both eradicate suffering and bestow happiness, and all can bestow both minor and major fruits of wisdom and merit; hence both are termed benefit and well-being. "Free from enmity, free from hostility, free from afflictive harm" are matched in turn with mental, vocal, and bodily karma. "Like the diverse convergence of the many currents of the four great rivers": this is a metaphor for the four immeasurables being the gathering of numerous wholesomenesses.
