俱舍論疏 8.5

8.5

「論曰至是名欲界」，總出欲界體也。即欲界中，若是有情、若器世間，總是欲界。趣唯有情，界兼無情。

"The treatise says: ... this is called the desire realm." This generally identifies the entity of the desire realm. Within the desire realm, whether sentient beings or the receptacle world, all are the desire realm. Destinies include only sentient beings; realms encompass also the insentient.
