摩訶止觀 7.86

7.86

若攀緣瞋恚，當用慈心為治。上忍度是通治，今別約慈無量心。餘三心或是樂欲等（云云）。悲無量為對治者，緣眾生苦，深起愍傷，欲拔其苦，緣此心入定，與悲相應。慈者，想眾生得樂，緣此心入，與慈定相應。喜心者，想眾生得樂，生大歡喜，緣此心入，與喜定相應。捨心者，捨愛憎想，住平等觀，緣此心入，與捨定相應。得此四定者，於諸眾生瞋無從生。下更廣說。

If one clings to anger, one should use the mind of loving-kindness (maitrī) as the remedy. The above pāramitā of patience is a general remedy; here we specifically address the immeasurable mind of loving-kindness. The other three minds are based on aspiration and so forth. Compassion as the remedy means: conditioning the suffering of sentient beings, giving rise to deep sorrow and wishing to pull them out of suffering; entering dhyāna conditioned on this mind, one accords with compassion. Loving-kindness means imagining sentient beings obtaining joy; entering conditioned on this mind, one accords with the dhyāna of loving-kindness. Joy means imagining sentient beings obtaining joy and giving rise to great delight; entering conditioned on this mind, one accords with the dhyāna of joy. Equanimity means abandoning thoughts of love and hate, abiding in the contemplation of equality; entering conditioned on this mind, one accords with the dhyāna of equanimity. One who attains these four dhyānas will have no way for anger toward sentient beings to arise. This will be explained in greater detail below.
