大方便佛報恩經 3.51

3.51

佛告阿難：「人生世間，禍從口生，當護於口，甚於猛火。猛火熾然能燒一世，惡口熾然燒無數世；猛火熾然燒世間財，惡口熾然燒七聖財。是故阿難！一切眾生禍從口出。口舌者，鑿身之斧，滅身之禍。」

The Buddha told Ānanda: “When humans are born in the world, misfortune arises from the mouth. One should guard the mouth more than [one fears] a raging fire. A blazing raging fire can burn [only] a single lifetime, but blazing harsh speech burns countless lifetimes; a blazing raging fire burns worldly wealth, but blazing harsh speech burns the seven noble treasures. Therefore, Ānanda, all misfortune of sentient beings comes forth from the mouth. The mouth and tongue are the axe that carves the body and the disaster that destroys it.”
