第二勝處遍處指如前說，謂前八解脫中，已對辨訖，故此不論，四無色定即四無色解脫。決擇等中釋四無色不異解脫，故亦不解。

Second, the stations of mastery (abhibhv-āyatana) and stations of totality (kṛtsnāyatana) are referred to as explained before; that is, they have already been comparatively analyzed in the eight liberations earlier, so they are not discussed here. The four formless concentrations are precisely the four formless liberations. In the Viniścaya[-saṃgrahaṇī] and so forth, it explains that the four formless [concentrations] do not differ from the liberations, hence they are also not explained here.
