Dhammapada · 12.8

Yo sāsanaṃ arahataṃ, ariyānaṃ dhammajīvinaṃ;Paṭikkosati dummedho, diṭṭhiṃ nissāya pāpikaṃ;Phalāni kaṭṭhakasseva, attaghātāya phallati.

Yo sasanam arahatam, ariyanam dhammajivinam; Patikkosati dummedho, ditthim nissaya papikam; Phalani katthakasseva, attaghataya phallati.

The fool who, relying on evil views, reviles the teachings of the arahants and noble ones who live by the Dhamma — ripens fruits, like the bamboo, that lead to his own destruction.
