佛說五無返復經 1.24

1.24

The brahmacārin said to the Buddha, "I saw a father and son plowing the ground and sowing seed. When the son died on the ground, the father felt no sorrow, but instead asked for food, and on the contrary spoke to me about impermanence. The mother, the wife, the sister, and the slave were likewise completely without sorrow or grief. This is utterly unnatural, lacking all human feeling."
