「如是所說至非諸無色」者，此下第二別明八等至。就中，一別明靜慮、二明三等至。就第一別明靜慮中，一明靜慮支、二明靜慮支體性、三明染無支、四明名不動、五明生受異、六明起下心。此即第一明靜慮支，故先標宗。如是所說八等至中，靜慮攝支，止、觀等故。非諸無色，止增、觀減。由此未至及中間定亦不立支，觀增、止減。

Regarding 'Among these as explained... not the formless states': below, this is the second section, specifically explaining the eight attainments. Within this, there are: first, specifically explaining the dhyāna; second, explaining the three attainments. Within the first, specifically explaining the dhyāna: first, explaining the dhyāna factors; second, explaining the intrinsic nature of the dhyāna factors; third, explaining defiled states lacking factors; fourth, explaining the name immovable; fifth, explaining differences in feeling upon rebirth; sixth, explaining the arising of lower minds. This is the first, explaining the dhyāna factors, hence the thesis is presented first. Among the eight attainments explained in this manner, the dhyānas subsume factors because calming and insight are balanced; this is not so for the formless states, where calming is predominant and insight is deficient. For this reason, the threshold and intermediate absorptions do not establish factors either, because insight is predominant and calming is deficient.
