成唯識論述記 7.337

7.337

述曰：論主初且理抑橫生異義，却斷亦無失。如何等如生上二界，却斷下第七中惑，以必金剛心方斷故。後正義解。

The Commentary states: The treatise master first momentarily constrains the objection by advancing an alternative position: turning back and severing them would also entail no fault. How is it so? Just as when born in the upper two realms, one turns back to sever the afflictions in the lower seventh [consciousness], because they must be severed only at the vajropama-samādhi. Afterward he explains according to the orthodox view.
