釋禪波羅蜜次第法門 6.155

6.155

復次，無想有三義：一、無想天定；二、非有想非無想定；三、滅受想定。無方便外道滅心，入無想天定；有方便凡夫外道滅心，入非有想非無想定；佛弟子滅心，入滅受想定。

Furthermore, non-perception has three meanings: first, the absorption of the heaven of non-perception; second, the absorption of neither having perception nor non-perception; third, the absorption of the cessation of sensation and perception. Non-Buddhists without expedient means extinguish the mind and enter the absorption of the heaven of non-perception; ordinary persons and non-Buddhists with expedient means extinguish the mind and enter the absorption of neither having perception nor non-perception; disciples of the Buddha extinguish the mind and enter the absorption of the cessation of sensation and perception.
