大乘義章 11.71

11.71

相資別者，四行相資相順難闕，故立四種。云何相資？先就慈悲明相資助。慈欲與樂，無悲拔苦與樂不成，由悲拔苦與樂方熟，故悲資慈。悲欲拔苦，無慈與樂苦終不去，由慈與樂苦方可離，故慈資悲。次用慈悲共喜相資。慈欲與樂、悲欲拔苦，無喜除嫉與拔不成，由善除嫉與拔方熟，故用喜心資成慈悲。喜欲慶物，若無慈悲拔苦與樂即無所慶，由慈與樂悲拔物苦方隨慶喜，故用慈悲助成喜心。次以前三共捨相助。慈欲與樂、悲欲拔苦、喜欲慶物，若無捨心簡別怨親不能普利，由捨除礙，方能齊與俱拔等慶，故用捨心資成前三。捨欲等利，若無前三與樂拔苦慶物隨喜，知何所等？由前三故就之說等，故將前三資成捨行。又復前三是其有行、捨是空行，若無空捨，有成愛見，故用捨心資成前三。若無有行，空成涕沒，故以前三資成空捨。以此四行相資相順，故須齊立，故《涅槃》云「伴侶相對，故分四矣。」制立如是。

As for the difference in mutual assistance: the four practices mutually assist and accord with one another and are hard to dispense with; therefore, four kinds are established. How do they mutually assist? First, explain mutual assistance regarding loving-kindness and compassion. Loving-kindness desires to bestow bliss; without compassion eradicating suffering, bestowing bliss cannot succeed; due to compassion eradicating suffering, bestowing bliss then matures; therefore, compassion assists loving-kindness. Compassion desires to eradicate suffering; without loving-kindness bestowing bliss, suffering is never removed; due to loving-kindness bestowing bliss, suffering can then be departed from; therefore, loving-kindness assists compassion. Next, loving-kindness and compassion mutually assist together with sympathetic joy. Loving-kindness desires to bestow bliss and compassion desires to eradicate suffering; without sympathetic joy removing jealousy, bestowing and eradicating cannot succeed; due to sympathetic joy removing jealousy, bestowing and eradicating then mature; therefore, the mind of sympathetic joy is used to assist and accomplish loving-kindness and compassion. Sympathetic joy desires to celebrate beings; if there were no loving-kindness and compassion eradicating suffering and bestowing bliss, there would be nothing to celebrate; due to loving-kindness bestowing bliss and compassion eradicating beings' suffering, one then rejoices and celebrates in accord; therefore, loving-kindness and compassion are used to help accomplish the mind of sympathetic joy. Next, the first three mutually assist together with equanimity. Loving-kindness desires to bestow bliss, compassion desires to eradicate suffering, and sympathetic joy desires to celebrate beings; without the mind of equanimity discriminating between enemies and kin, one cannot universally benefit; due to equanimity removing obstructions, one is then able to bestow equally, eradicate together, and celebrate impartially; therefore, the mind of equanimity is used to assist and accomplish the first three. Equanimity desires to benefit equally; without the first three bestowing bliss, eradicating suffering, and celebrating beings with sympathetic joy, what would there be to equalize? Because of the first three, equality is spoken of in relation to them; therefore, one takes the first three to assist and accomplish the practice of equanimity. Furthermore, the first three are practices of existence, while equanimity is a practice of emptiness; without the equanimity of emptiness, existence becomes craving and views; therefore, the mind of equanimity is used to assist and accomplish the first three. If there were no practice of existence, emptiness would become drowning and sinking; therefore, the first three are used to assist the equanimity of emptiness. Because these four practices mutually assist and accord with one another, all must be established together; hence the Nirvāṇa [Sūtra] states: 'Being companions and facing one another, they are therefore divided into four.' Their formulation is like this.
