and all the mental phenomena they become conscious of will be repulsive. None will be attractive; they will all be unpleasant. None will be pleasant; they will all be dislikeable. None will be likeable; they will all be disagreeable. None will be enjoyable. Their bodies will be consumed by fire; they will eat lumps of iron and drink molten iron and copper. On that basis, they will experience harsh, unbearable, and scorching feelings of suffering in those places. Until the physical, verbal, and mental negative actions they committed in the past when they were born here among humans have been exhausted and purified, they will not die and transmigrate from those places. Kauṇḍinya, consider this: what sentient being who wishes for happiness and feels aversion toward suffering would enjoy and wish for those hells? This is the first destiny of those who engage in negative actions, toward which the wise ones should generate the perception of dislike.

“Kauṇḍinya, how should the wise ones generate the perception of dislike toward the condition of the animals? Kauṇḍinya, there are animals who are born with extremely small bodies: some are born with bodies about the size of the fiftieth fraction of the tip of a hair, others with bodies about the size of dust motes in the sunlight, and yet others with bodies about the size of jujube fruits. Still others obtain bodies up to ten thousand leagues long. The lifespan of some of them lasts for a single instant, whereas the life of others stretches over an eon. In those places, animals do not practice the Dharma or engage in virtue. They have abandoned modesty and humility, they are lacking in compassion and sympathy, they are constantly tormented by suffering, they are always afraid, they eat each other, and they follow all the paths of the nonvirtuous actions.
