Author Amitav Ghosh speaks about metempsychosis—the idea of the transmigration of souls into any life form—one of the key themes in Ghost Eye. He points out that the concept has been acknowledged across traditions, from Buddhism to ancient Greek thought, noting that Plato’s Republic ends with a detailed discussion on metempsychosis and that Agamemnon, in the Iliad, chooses to be reborn as an eagle rather than as a human.
