The Long Āgama Sūtra 21.9

21.9

爾時，世尊告諸比丘：「若有方便毀謗如來及法、眾僧者，汝等不得懷忿結心，害意於彼，所以者何？若誹謗我、法及比丘僧，汝等懷忿結心，起害意者，則自陷溺，是故汝等不得懷忿結心，害意於彼。比丘若稱譽佛及法、眾僧者，汝等於中亦不足以為歡喜慶幸，所以者何？若汝等生歡喜心，即為陷溺，是故汝等不應生喜。所以者何？此是小緣威儀戒行，凡夫寡聞，不達深義，直以所見如實讚嘆。

The Bhagavān then told the monks, “If someone criticizes the Tathāgata, Dharma, and the Saṅgha in some way, don’t allow yourselves to feel angry and have harmful intent toward them. Why is that? If they criticize me, the Dharma, and Saṅgha of monks and you feel angry and have harmful intent, it’ll result in your own downfall; therefore, don’t allow yourself to feel angry and have harmful intent toward them.

“Monks, if someone praises the Buddha, Dharma, and Saṅgha, that isn’t enough for you to feel delighted and rejoice. Why is that? If you feel delighted, then it will be your downfall; therefore, you shouldn’t feel delighted. Why is that? These are minor matters of deportment and observing precepts. Ordinary, uneducated people don’t penetrate the [Dharma’s] profound meaning, so they praise only what they see [with their eyes].
