so pan' esa aṭṭhamī-cātuddasī-pannarasī-bhedena tividho. Tasmā sesa-dvaya-nivāraṇatthaṃ pannarase ti vuttaṃ.
The context is a discussion on the Uposatho:
"The Uposatha is three-fold, consisting of the eighth day, fourteenth day and fifteenth day. It is called "on the fifteenth" on account of preventing the remaining two" ? Does the "remaining two" refer to the eighth and fourteenth?
Best wishes,
