法苑珠林 24.11

24.11

復次能說法者。復有二種。一者清淨。二者不清淨。不清淨者復有五事。一為利故說。二為報而說。三為勝他說。四為十報說。五疑說。

Furthermore, among those who are able to explain the Dharma, there are two kinds: the first is pure, and the second is impure. The impure again has five matters: first, speaking for the sake of profit; second, speaking for the sake of retribution; third, speaking to surpass others; fourth, speaking for the sake of worldly reward; fifth, speaking with doubt.
