Lord of Light by Roger Zelazny:
Science Fiction Inventions, Technology and Ideas

Another classic by Roger Zelazny; it won the Hugo for its year. Colonists from Earth have founded another world; a science of body swapping is developed that makes "reincarnation" a fact. Don't cross the lords of karma; you might be reborn as a dog. The ultimate individualist, the Mahasamatman, takes a body to fight the good fight. But call him Sam. Select an invention:

Mechanical Cobra - slither and destroy
An assassination device; senses brain waves to find its victim.

Pray-Machine - megawatts of prayer
A kind of energy receiver that could retrieve a soul from the radiation belt surrounding a planet.

Pray-o-Mat - coin-based religion
A device that would offer prayers in exchange for a few coins properly deposited.

Scientific Reincarnation
Technology to allow a person to transfer themselves to a new, healthy body.
