大般涅槃經義記 8.63

8.63

下明喜捨，「於諸眾生不瞋」是喜，「不喜」是捨。初先正辯，「德王白」下問答重顯。前正辯中，初先法說，「菩薩於生不瞋、不喜」略舉喜捨。「何以」下釋，以「善修集空三昧故」不生瞋、喜。次以喻顯，「林」喻菩薩，「火」等喻於能惱之人，「而是林」下喻無瞋喜。下合可知。

Below, sympathetic joy and equanimity are explained: "toward all sentient beings not being angry" is sympathetic joy; "not being delighted" is equanimity. First it explains directly; "King of Virtuous Qualities said..." and below clarifies this again through questions and answers. Within the former direct explanation, it first speaks in terms of the Dharma: "A bodhisattva toward sentient beings is neither angry nor delighted" briefly adduces sympathetic joy and equanimity. "Why?" and below explains: because of "well cultivating and gathering the samādhi of emptiness," anger and delight do not arise. Next it is revealed through an analogy: the "forest" is an analogy for the bodhisattva; the "fire" and so forth are an analogy for those who can afflict; "yet this forest..." and below is an analogy for having neither anger nor delight. The correspondence below can be understood.
