2.31

四無量者，謂慈、悲、喜、捨。四中初二，無瞋為體，喜即喜受、捨即無貪。所緣境者，欲界有情所有瞋害，及有欣慰欲貪瞋等，如次對治。

The four immeasurables are loving-kindness, compassion, sympathetic joy, and equanimity. Among the four, the first two have non-hatred as their essence; sympathetic joy is the feeling of joy; equanimity is non-greed. Their intentional objects are the hatred and malice, as well as the delight, desire, greed, and hostility of sentient beings in the desire realm, serving as antidotes respectively.
