襃灑陀（上保毛反次沙假反梵語也此云長淨即半月和合說戒增長淨法也舊云布薩訛也）。

Poṣadha (襃灑陀: the upper character has the fanqie 保毛; the next has the fanqie 沙假; Sanskrit; translated here as "perpetual purification", that is, the harmonious reciting of precepts every half-month to increase pure dharmas; formerly rendered 布薩, which was corrupted).
