Galactic Pot Healer by Philip K. Dick

In a universe where reality is as malleable as clay, a disillusioned pot repairman is summoned by a mysterious alien entity to a distant planet for a cosmic restoration project. As he joins a motley crew of beings from across the galaxy, he grapples with existential questions and the nature of his own identity. Amidst the backdrop of a crumbling underwater cathedral, the protagonist confronts the boundaries of faith, purpose, and the power of belief, ultimately discovering that the true act of healing lies within the self.
