釋禪波羅蜜次第法門 6.157

6.157

答曰：不善滅無所有中心數法故非妙。復次，若在色界，無想為極；若在無色界，非有想非無想為極。若佛法中，自有滅、受、想，不用處於三處中皆非勝定，故不取也。

Answer: Because it does not skillfully extinguish the mental factors within nothingness, it is not sublime. Furthermore, in the form realm, non-perception is the utmost; in the formless realm, neither-having-perception-nor-non-perception is the utmost. In the Buddhadharma, there is intrinsically the cessation of sensation and perception. The base of non-employment is not a superior absorption among any of these three places, and therefore it is not included.
