The Long Āgama Sūtra 8.25

8.25

佛告梵志：「彼苦行者，常自計念：『我行如此，當得供養恭敬禮事。』是即垢穢。彼苦行者，得供養已，樂著堅固，愛染不捨，不曉遠離，不知出要，是為垢穢；彼苦行者，遙見人來，盡共坐禪，若無人時，隨意坐臥，是為垢穢。

The Buddha told the ascetic, “Those practitioners of asceticism often think to themselves, ‘Practicing in this way, I’ll obtain offerings, respect, and veneration.’ This is a defilement. After they obtain offerings, that practitioner’s attachment to pleasure is made firm, and the stains of craving aren’t abandoned. They don’t realize how to distance themselves from it or know how to escape it. This is a defilement.

“Those practitioners of asceticism see someone coming from a distance, and they all sit together in meditation. When no one else is present, they sit and lie down as they like. This is a defilement.
