法苑珠林 24.12

24.12

清淨說者。復有五事。一先施食然後說。二為增長三寶故說。三斷自他煩惱故說。四為分別邪正故說。五為聽者得最勝故說。善男子。不淨說法者。名曰垢穢。名為賣法。亦名污辱。亦名錯說。亦名失意（清淨說者翻前即是）。

The pure speaker also has five matters: first, first giving food and only then speaking; second, speaking to increase the Three Jewels; third, speaking to sever afflictions in oneself and others; fourth, speaking to distinguish the heterodox from the orthodox; fifth, speaking so that listeners attain the supreme. Good sons, an impure preacher of the Dharma is called defiled, is called a seller of the Dharma, is also called a polluter, is also called an erroneous speaker, and is also called one who has lost their mind. (The pure speaker is simply the reverse of the above.)
