"Lord Of Light is a novel about a future world after the destruction of Earth, conquered by men who, through ultratechnology, give themselves godlike powers and set themselves up as the old Hindu gods to rule the common people. Called The First, they have achieved a kind of immortality by transferring their identities from old bodies to new ones. These deicrats (as Zelazny calls them) through centuries of "divine" rule, have become corrupt, and only one among them will openly oppose their tyranny. He is the hero, "who was variously known as Mahasamatman, Kalkin, Manjusri, Siddhartha, Tathagatha, Binder, Maitreya, the Enlight-ened One, Buddha and Sam.""
