首楞嚴義疏注經 9.80

9.80

「阿難！此不還天，彼諸四禪四位天王獨有欽聞，不能知見。如今世間曠野深山、聖道場地，皆阿羅漢所住持故，世間麁人所不能見。」

"Ānanda, regarding these Non-Returning Heavens, the heavenly kings of those four stages of the fourth dhyāna only hear of them with veneration, but cannot know or see them, just as nowadays in the mundane realm, in the wilderness, deep mountains, and places of holy bodhimaṇḍas, because they are maintained by arhats, crude people of the mundane realm cannot see them."
