power explained

One who wields the Rinnegan can utilise six abilities collectively known as the Six Paths Technique: controlling attractive and repulsive forces with the Deva Path; mechanically altering one's body with the Asura Path; extracting souls through the Human Path;  summoning various creatures through the Animal Path;  absorbing chakra through the Preta Path; and access to the King of Hell through the Naraka Path. A seventh ability, called the Outer Path, is said to allow the user to preside over life and death, granting them the ability to revive the dead.The Outer Path also allows the user to transmit their chakra into black receivers, manifest chakra chains to bind the tailed beasts, and create the Six Paths of Pain: six bodies controlled through the use of black receivers, which can each utilise one aspect of the Six Paths Technique. The Rinnegan grants the user a shared field of vision with their Six Paths of Pain, the creatures summoned through the Animal Path, and the King of Hell, all of which possess copies of the Rinnegan in their own eyes.
