大方廣佛華嚴經隨疏演義鈔 59.15

59.15

疏「既言具苦必知無樂」者，此遮妨難。恐有問言：慈是與樂，經中但言見生有苦，何言興慈？故通云爾。然經慈悲二觀影略，悲中覩境却無拔濟之言，慈中闕於覩境却兼拔濟之語，二觀同緣有苦故。「生慈」下，重舉前境，以明拔濟，成上之悲。置安樂處，生下之慈，義皆足矣。

The Commentary states: "Since it says 'complete with suffering,' one must know there is no joy": this forestalls an objection. Fearing that someone might ask: loving-kindness is giving joy, but the sūtra only speaks of seeing that sentient beings have suffering; why does it speak of giving rise to loving-kindness? Therefore it resolves it in this way. However, the sūtra's two contemplations of loving-kindness and compassion complement each other: in compassion, beholding the object lacks words of deliverance, while in loving-kindness, it lacks beholding the object yet includes words of deliverance, because both contemplations equally take having suffering as their object. "Giving rise to loving-kindness [and following]" reiterates the preceding object to clarify deliverance, accomplishing the compassion above. Establishing them in a place of peace and joy gives rise to the loving-kindness below, and the meaning is completely fulfilled.
