俱舍論頌疏論本 12.44

12.44

問：「若爾，彼地器應是常。」答：「頌言『然彼器非常，情俱生滅故。』謂彼天處無總地形，但如眾星居處各別。彼天生時天宮隨起，彼天死時天宮隨滅。」

Question: 'If so, the physical realm of that stage should be permanent.' Answer: 'The verse says, "Yet its physical world is impermanent, because it is produced and destroyed together with the sentient beings." This means that in that celestial realm there is no collective earth mass; they merely dwell separately like stars. When those devas are born, the celestial palaces arise accordingly; when those devas die, the celestial palaces perish accordingly.'
