14.84

又智度論云。或有餓鬼。先世惡口。好以麁語加彼眾生。眾生增惡。見之如讎。以此罪故墮餓鬼中。又法句經云。雖為沙門。不攝身口。麁言惡說。多所中傷。眾所不愛。智者不惜。身死神去輪轉三塗。自生自死苦惱無量。諸佛賢聖所不愛惜。假令眾生。身雖無過。不慎口業。亦墮惡道。故論云。時有一鬼。頭似猪頭。臭蟲從口出。身有金色光明。是鬼宿世作比丘。惡口罵詈客比丘。身持淨戒故身有光明。口有惡言故臭蟲從口出。

Also, the Dazhidu lun says: “There are hungry ghosts who in past lives had harsh speech and took pleasure in applying coarse words to those sentient beings. Sentient beings increased in detesting them, seeing them like enemies. Due to this transgression they fell among hungry ghosts.” Also, the Dharmapada says: “Though one is a śramaṇa, if one does not restrain body and mouth, using coarse words and evil speech, inflicting much wound and injury, one is not loved by the multitude, nor cherished by the wise. When the body dies and the consciousness departs, one transmigrates in the three wretched paths, suffering immeasurable torment through self-born and self-died states, unloved and unspared by all Buddhas, worthies, and sages. Even if a sentient being has no faults of the body, if they do not guard the karma of the mouth, they will also fall into the evil destinies.” Therefore the treatise says: “Once there was a ghost whose head was like a pig's head, with foul maggots emerging from its mouth, but its body had golden light. This ghost in a past life had been a bhikṣu who reviled and cursed visiting bhikṣus with harsh speech. Because his body had kept the pure precepts, his body had light; because his mouth had evil words, foul maggots emerged from his mouth.”
