Summary
Analysis
One day there is a thunderstorm and lightning strikes the water near the lifeboat. Pi grows ecstatic at the sight and praises God for this “miracle,” but Richard Parker cowers trembling on the floor of the boat. Pi remembers this storm and his feeling of exalted wonder as one of his happiest moments at sea.
Pi accepts this lightning strike as a sign from God, an act of communication with the religion that seems to have forsaken him. Pi lives on the edge of death every day, so the lightning inspires wonder in him instead of fear.
