大般涅槃經義記 8.328

8.328

「雖生惡國，以道力故不作惡」者，釋第三中云何而得不作惡業，明由道力。初先法說，「如香山」下四喻顯之。就初喻中，「譬如香山有師子王」，喻須陀洹現陰身中有無漏道。「一切鳥獸無敢近」者，喻惡不生。「有時是王至雪山」者，喻無漏道流至末後得道身中。「一切鳥獸猶不住」者，不敢住於空香山中。彼空香山喻須陀洹中間所受無道之身，由前道故惡業不行。下合可知。後之三喻併舉總合，文皆可識。

As for "Although they are born in an evil country, by the power of the Path they do not commit evil," this explains how they can avoid committing evil karma in the third [difficulty], clarifying that it is due to the power of the Path. First comes the doctrinal statement, and below, beginning with "Like the Fragrant Mountains," four analogies illustrate it. Within the first analogy, "Suppose, for example, that in the Fragrant Mountains there is a lion king" is an analogy for the unoutflowing Path being present in the current aggregate-body of a srotāpanna. "No birds or beasts dare approach" is an analogy for evil not arising. "At times this king goes to the Snow Mountains" is an analogy for the unoutflowing Path continuing on until it reaches the final body in which the Path is attained. "None of the birds or beasts dwell there even then" means that they dare not dwell in the empty Fragrant Mountains. That empty Fragrant Mountain is an analogy for the intermediate Pathless body received by the srotāpanna; because of the previous Path, evil karma does not take place. The matching explanation below can be understood. The latter three analogies are presented together and matched as a whole; their text is easily understood.
