注維摩詰經 4.126

4.126

肇曰：夫慈生愛，愛生著，著生累。悲生憂，憂生惱，惱生憎。慈悲雖善而累想已生，故兩捨以平等觀，謂之捨行也。

[Seng]zhao says: Loving-kindness engenders affection, affection engenders grasping, and grasping engenders encumbrance. Compassion engenders grief, grief engenders affliction, and affliction engenders hatred. Although loving-kindness and compassion are good, encumbering thoughts have already arisen. Therefore, renouncing both to contemplate with equanimity is called the practice of equanimity.
