首楞嚴義疏注經 9.366

9.366

「口中好言未然禍福，及至其時毫髮無失。此大力鬼，年老成魔，惱亂是人。厭足心生，去彼人體，弟子與師俱陷王難。汝當先覺，不入輪迴；迷惑不知，墮無間獄。」

"His mouth loves to speak of misfortunes and blessings before they happen, and when the time arrives, there is not the slightest discrepancy. This is a powerful ghost that in old age has become a demon, troubling and disordering this person. When satiety arises [in the demon], it leaves that person's body; disciple and master alike fall into calamity under the law. You should awaken to this beforehand and not enter the cycle of rebirth; if you are deluded and unaware of it, you will fall into the Avīci Hell."
