One day, the Buddha was strolling alone along the edge of a lotus pond in Paradise. The blooming lotus flowers in the pond were each pure white like jewels, and the place was filled with the indescribably wondrous fragrance continually emitted from each flower's golden center. It was just morning in Paradise.

After a time, the Buddha paused at the edge of the pond and from between the lotus leaves that covered it saw a glimpse of the state of things below. Now this celestial pond just happened to lie directly over Hell, and peering through that crystal-clear water was like looking through a magnifying glass at the River of Death and the Mountain of Needles and such.

The Buddha saw there, in the depths of Hell, a single man writhing along with the other sinners. This man was named Kandata, and he had been a notorious thief who had performed murder and arson and other acts of evil. In his past, however, he had performed just one good deed: one day, when walking through the deep forest, he saw a spider crawling along the road. At first he raised his foot to crush it, but suddenly he changed his mind and stopped, saying, "No, small though it may be, a spider, too, has life. It would be a pity to meaninglessly end it," and so did not kill it.

Looking down upon the captives in Hell the Buddha recalled this kind act that Kandata had performed, and thought to use his good deed as a way to save him from his fate. Looking aside, there on a jade-colored lotus leaf he saw a single spider, spinning out a web of silver thread. The Buddha carefully took the spider's thread into his hand, and lowered it straight down between the jewel-like white lotuses into the depths of Hell.
