29.6

與樂及拔苦，欣慰有情等者，明行相也。與樂是慈；拔苦是悲；欣慰是喜；有情等是捨，謂怨親平等，捨怨捨親，名為捨也。願諸有情得如是樂，如是思惟，入慈等至。願諸有情離如是苦，如是思惟，入悲等至。諸有情類得樂離苦，豈不快哉，如是思惟，入喜等至。諸有情類平等平等，無有怨親，如是思惟，入捨等至。

'Granting bliss and removing suffering, rejoicing, and being equal toward sentient beings' explains their aspects. Granting bliss is benevolence; removing suffering is compassion; rejoicing is sympathetic joy; being equal toward sentient beings is equanimity, meaning being equal toward enemies and friends, casting aside enemies and casting aside friends; hence it is called 'equanimity'. Thinking, 'May all sentient beings obtain such bliss,' one enters the absorption of benevolence. Thinking, 'May all sentient beings be free from such suffering,' one enters the absorption of compassion. Thinking, 'That sentient beings have obtained bliss and are free from suffering—how delightful!' one enters the absorption of sympathetic joy. Thinking, 'All sentient beings are entirely equal, without enemy or friend,' one enters the absorption of equanimity.
