Lord of Light
Lord of Light (1968) is an epic science fiction/fantasy novel by Roger Zelazny. It was awarded the 1968 Hugo Award for Best Novel, and nominated for a Nebula Award in the same category.
It is set on a planet ruled by a group who have used advanced technology to set themselves up as gods, modelling themselves on Hindu deities and rewarding the faithful with reincarnation (provided using cloned bodies and mind transfer). The protagonist, Sam, is a renegade "god" who is trying to restore self-government to the people, using, among other techniques, Buddhism as a culture jamming tool.
Lord of Light is also the title of a song by Hawkwind, possibly named after the Zelazny novel, although there is no direct reference to it in the lyrics. Hawkwind also recorded songs based on Zelazny's Damnation Alley and Jack of Shadows.
