首楞嚴義疏注經 9.62

9.62

「阿難！此中復有五不還天，於下界中九品習氣俱時滅盡，苦樂雙亡，下無卜居，故於捨心眾同分中安立居處。」

"Ānanda, herein there are further the Five Non-Returning Heavens, wherein the nine grades of habitual tendencies in the lower realms are completely extinguished all at once; suffering and bliss both perish, and with no dwelling place below, their abodes are established within the shared character of the mind of equanimity."
