長阿含經 14.p79

14.p79

The Buddha told Lord Śakra, “There are three kinds of error: First is speech, second are concepts, and third are pursuits. Speech is words that harm oneself, harm others, and harm both oneself and others. When these words are abandoned, one’s words don’t harm oneself, don’t harm others, and don’t harm both oneself and others. When that’s known, a monk’s words are such that he focuses his attention and isn’t distracted.
