首楞嚴義疏注經 9.109

9.109

若從無想，用有漏道忻上厭下，漸至非想，認此有漏作無為解，便謂涅槃。至此不進，以不廣聞聖教、不辨諸禪漏與無漏修證行相，壽終隨業必入諸趣也。言從無想來者，應是廣果天來，與無想同地，對五聖天名為外道，是外道類，故云從無想來。若實入無想，必定退墮，更不進修。准經論釋，無想外道業盡必墮，無上生義故。

If from No Thought, using the path with outflows, they yearn for what is above and feel disgust for what is below, gradually reaching non-perception, they take this state with outflows to be the unconditioned and declare it to be nirvāṇa. Arriving here they do not advance; because they have not widely heard the noble teachings and do not distinguish the cognitive aspects of cultivating and realizing the various dhyānas with and without outflows, when their lifespan ends they will inevitably enter the various destinies in accord with their karma. The statement 'come from No Thought' must mean coming from the Heaven of Vast Results, which shares the same ground with No Thought; in contrast to the five noble heavens it is called non-Buddhist, being of the non-Buddhist class; hence it says 'come from No Thought'. If one actually enters No Thought, one will certainly retrogress and fall, and will not cultivate further. In accordance with sūtras and treatises, when the karma of a non-Buddhist in No Thought is exhausted, they inevitably fall, because there is no possibility of ascending birth.
