23.30

依欲界身九者，依身門。此煗等四唯依欲界人、天身起，除北俱盧，人趣三洲及六欲天也。九處身起，唯依欲者，能厭苦故。前三善根三洲初起，後生六天，亦續現前。第四善根天亦初起，謂第四善唯一念故，故人天趣皆得初起。

"Relying on the body in the desire realm, nine": the gate of relying on bodies. These four—heat and the rest—arise only relying on the bodies of humans and devas of the desire realm, excluding Uttarakuru: the three continents of the human destiny and the six desire heavens. Arising in these nine bodily states, they rely only on desire because [those beings] can feel revulsion toward suffering. The first three roots of goodness initially arise in the three continents, and upon subsequent birth into the six heavens, they may also continue to manifest. The fourth root of goodness also initially arises in the heavens; that is, because the fourth wholesome [root] is only a single moment, it can initially arise in both human and deva destinies.
