成唯識論演祕 6.51

6.51

釋曰：如求滅定起無漏惠，無想不爾，故云「無惠」。以滅盡定在無想上，名「此上有勝寂靜住」。上有無色四處可生，名為「生」也；或五淨居是聖生處，名為「生」也。如阿羅漢必依滅定證無餘依，無想不然，云「未證得諸勝善法」。或入滅盡前方便中入色、無色諸有漏定，名「證善法」，無想不爾。由此多因，故聖不入。

The explanation says: Like seeking the absorption of cessation, one gives rise to anāsrava wisdom; non-conception is not like this, so it says 'no wisdom'. Because the absorption of cessation is above non-conception, it is called 'above this there is a superior peaceful abiding'. Above, there are four abodes of the formless realm where one can be born, which is called 'birth'; alternatively, the five pure abodes are places of birth for noble ones, which is called 'birth'. Just as the arhat must rely on the absorption of cessation to realize [nirvāṇa] without remainder, non-conception is not so, hence it says 'cannot attain superior wholesome phenomena'. Alternatively, in the preparatory stage prior to entering cessation, one enters various sāsrava absorptions of the form and formless realms, which is called 'attaining wholesome phenomena'; non-conception is not so. Due to these many reasons, the noble ones do not enter it.
