Moreover, the Hell Sūtra says: 'If a disciple speaks of the faults of their master or monks, even if the master truly has them, at the end of life that disciple will surely enter hell and have their tongue eaten away. If one obtains good food, delicious fruit, and the like, and does not give it first to parents, masters, or monks, but eats it oneself, one falls among the hungry ghosts, and afterward is born among humans in poverty. If a person harbors venom toward their masters or elders, they enter the Iron Stake Hell, and afterward are born among venomous snakes. If with an evil mind one mimics the speech of parents, masters, or elders, one enters the Molten Copper Hell, and afterward is born among humans with a stammer.'
