俱舍論疏 29.16

29.16

論「此四無量至入捨等至」，述四行相別。《正理論》云「此阿世耶有差別者，觀有情類如己謂慈，樂有情類離苦謂悲，於他興盛欣慰謂喜，於親、怨相不思謂捨。」《婆沙》八十一云「尊者世友作如是說：授與饒益是慈相，除去衰損是悲相，慶慰得捨是喜相，忘懷平等是捨相（已上論文）。」

The Śāstra states: "These four immeasurables... up to: enter the attainment of equanimity." This relates the distinctions among the four modes of activity. The Nyāyānusāra states: "Regarding the differences among these intentions (āśaya): contemplating sentient beings as oneself is love; desiring sentient beings to be free from suffering is compassion; rejoicing in the prosperity of others is sympathetic joy; not reflecting on the characteristics of friends and enemies is equanimity." The Vibhāṣā, fascicle 81, states: "The Venerable Vasumitra spoke thus: Bestowing benefit is the characteristic of love; removing decline is the characteristic of compassion; rejoicing in their attainment is the characteristic of sympathetic joy; abandoning partiality in impartiality is the characteristic of equanimity (thus far the text)."
