The Long Āgama Sūtra 8.33

8.33

「彼苦行者，精勤不忘，好習禪行，多修智慧，不愚如獸，是為苦行離垢法也；彼苦行者，不為高貴、憍慢、自大，是為苦行離垢法也；彼苦行者，常懷信義，修反復行，能持淨戒，勤受訓誨，常與善人而為伴黨，積善不已，是為苦行離垢法也；彼苦行者，不懷瞋恨，不為巧偽，不恃己見，不求人短，不懷邪見，亦無邊見，是為苦行離垢法也。云何，梵志！如是苦行，為是清淨離垢法耶？」

“Those ascetic practitioners are diligent, not forgetful, prefer the practice of meditation, and often cultivate wisdom. They aren’t foolish like animals. This is an ascetic practice that’s undefiled.

“Those ascetic practitioners aren’t conceited, proud, or arrogant. This is an ascetic practice that’s undefiled.

“Those ascetic practitioners are always trustworthy and cultivate the practice of repaying favors. They can observe pure precepts and diligently accept instruction. They associate with good people, consider them comrades, and don’t stop accumulating goodness. This is an ascetic practice that’s undefiled.

“Those ascetic practitioners don’t harbor resentment, aren’t deceptive, don’t rely on their own views, don’t look for other people’s shortcomings, and don’t harbor wrong or extreme views. This is an ascetic practice that’s undefiled.

“How is it, wanderer? Is such an ascetic practice pure and undefiled?”
