俱舍論疏 18.178

18.178

論「次算及文至五蘊為體」，明算、文體。算謂稱九九八十一等，文謂善巧安布五聲等。《婆沙》云「此中算者，非謂所算一、十、百、千等，但是所有能算之法故說為算。」又云「此中詩者，非所述詠，但是所有能成詠法。此能成詠，故說為詩（詩即文也）。」

On the treatise passage from "Next, calculating and composing" to "taking the five skandhas as intrinsic nature": This clarifies the intrinsic nature of calculating and composing. Calculating refers to reciting nine times nine is eighty-one, and the like; composing refers to skillfully arranging the five grammatical cases, and the like. The Vibhāṣā states: "Herein, 'calculating' does not mean the one, ten, hundred, or thousand being counted, but whatever dharmas are capable of calculating; therefore it is called calculating." It also states: "Herein, 'poetry' is not what is recited, but whatever dharmas are capable of composing the recitation. Because this can compose the recitation, it is called poetry ('poetry' is precisely 'composing')."
