大乘義章 11.68

11.68

對患別者，如《涅槃》說。慈息貪欲；悲止瞋恚，經中亦云「悲止害覺」；喜除嫉妬，經中亦云「喜除不樂」，以嫉妬故，見他得利心不喜樂，故喜治之；捨除一切貪恚癡等。問曰：前說慈無瞋性，今云何說慈息貪欲？釋言：不違。若貪五欲，由惜資財便瞋眾生，不能與樂。由息貪故，於他不瞋，能與其樂。是故慈心性雖不瞋，能息貪欲（此四門竟）。

As for the difference in afflictions remedied: as the Nirvāṇa [Sūtra] states, loving-kindness quells covetous desire; compassion halts anger—the sūtra also says 'compassion halts malicious thoughts'; sympathetic joy removes jealousy—the sūtra also says 'sympathetic joy removes joylessness', because on account of jealousy, seeing others obtain gain, one's mind feels no joy or pleasure, and therefore sympathetic joy remedies it; equanimity removes all greed, anger, delusion, and so forth. Question: Previously it was said that loving-kindness is of the nature of non-anger; why is it now said that loving-kindness quells covetous desire? The explanation states: There is no contradiction. If one covets the five desires, through begrudging material property one will become angry with sentient beings and be unable to give them bliss. By quelling greed, one is not angry toward others and is able to bestow bliss upon them. Therefore, although the mind of loving-kindness by nature is non-anger, it can quell covetous desire (this completes the fourth section).
