Galactic pot-healer

the long version

Galactic Pot-Healer is a science fiction novel by American writer Philip K. Dick, first published in 1969. The novel deals with a number of philosophical and political issues such as repressive societies, fatalism, and the search for meaning in life. Dick also wrote a children's book set in the same universe, Nick and the Glimmung, in 1966. It was published posthumously in 1988. The story concerns a man who thanklessly heals pots in a totalitarian future Earth, only to be summoned by a godlike alien known as Glimmung, who has recruited him as part of a multispecies specialist team sent to "Plowman's Planet" (or Sirius Five) for a mystical quest, which is to raise the sunken cathedral of Heldscalla from a surreal alien ocean.
