俱舍論頌疏論本 29.4

29.4

釋曰：初句總標，次一句顯唯有四，次兩句出體，次三句明行相，次一句明所緣，次兩句明所依地，次一句明不斷惑，次一句明處及成。無量有四種者，一慈、二悲、三喜、四捨。言無量者，無量有情為所緣故，引無量福故，感無量果故。問：「此何緣唯有四種？」答：「頌言『對治瞋等故』（等取害等三障故也），此有四障：一瞋、二害、三不欣慰、四欲貪瞋。對治此四多行障故，建立慈等。」

Explanation: The first line marks the topic in general; the next line shows that there are only four; the next two lines reveal their intrinsic nature; the next three lines explain their aspects; the next line explains their object; the next two lines explain their grounds of dependence; the next line explains that they do not abandon afflictions; the next line explains their location and achievement. 'The immeasurables are four': first, benevolence; second, compassion; third, sympathetic joy; fourth, equanimity. They are called 'immeasurable' because they take immeasurable sentient beings as their object, because they induce immeasurable merit, and because they bring about immeasurable fruit. Question: 'For what reason are there only four?' Answer: 'The verse says, "because of counteracting hatred and the like" (the "and the like" includes the three obstacles such as malice); here there are four obstacles: first, hatred; second, malice; third, non-rejoicing; fourth, sensual greed and hatred. Because they counteract these four frequently occurring obstacles, benevolence and the rest are established.'
