佛說觀普賢菩薩行法經 1.46

1.46

「作是語已，五體投地遍禮十方佛，合掌長跪，當作是語：『此舌過患無量無邊，諸惡業刺從舌根出，斷正法輪從此舌起。如此惡舌斷功德種，於非義中多端強說、讚歎邪見如火益薪，猶如猛火傷害眾生、如飲毒者無瘡疣死。如此罪報惡邪不善，當墮惡道百劫、千劫，以妄語故墮大地獄。我今歸向南方諸佛，發露黑惡。』

"Having spoken these words, casting the five limbs to the ground, they bow everywhere to the Buddhas of the ten directions, and with palms joined, kneeling upright, they should speak these words: 'The faults and perils of this tongue are immeasurable and boundless; the thorns of all evil karma arise from the tongue faculty, and the cessation of the wheel of the true Dharma arises from this tongue. Such an evil tongue cuts off the seeds of merit, forcefully arguing on many fronts about what is not the truth, praising wrong views like adding firewood to a fire, harming living beings like a raging fire, and dying without sore or boil like one who has drunk poison. For such retribution of sinful, evil, and unwholesome deeds, one must fall into the evil destinies for hundreds of kalpas and thousands of kalpas; because of false speech one falls into the great hells. I now take refuge in the Buddhas of the southern direction and confess my dark evils.'
