soccāṇaṃ pharusā bhāsā | dāruṇā gāmakaṇagā /
tusiṇīo uvehejjā | na tāo maṇasī kare ||25||

If a layman abuses a monk, he should not grow angry against him; because he would be like a child, a monk should not grow angry. (24)
If a monk hears bad words, cruel and rankling ones, he should silently overlook them, and not take them to heart. (25)
