Six Paths Technique

The is the origin of the unique techniques bestowed by the Rinnegan infused with Hagoromo Ōtsutsuki's chakra. Despite its name, there is actually in total seven of these paths that grant the user powerful and near god-like abilities:
 * The, which allows one to manipulate both attractive and repulsive forces.
 * The, which grants the user mechanised limbs, weaponry and armour.
 * The, which gives the ability to remove a soul and so, read a person's mind.
 * The, which lets the user summon a wide variety of creatures.
 * The, which can absorb all forms of chakra, including most ninjutsu.
 * The, through which one can summon and control the King of Hell.
 * The, which rules over both life and death.

These were all originally abilities that were used by one person, but because Nagato was crippled early on in his lifetime, he would go on to create the Six Paths of Pain. Through the use of the Outer Path, he was able to control six corpses as additional bodies and channel one of the first six of the aforementioned abilities into each, thus compensating for his physical limitations. However, while the strength and speed of the techniques are greater when used through the main body than when used through the corpses, and multiple Paths can also be activated simultaneously by the main body, there are advantages granted by the use of corpses. As the main body's vision is linked to the Rinnegan possessed by the corpses, the user is able to easily coordinate their movements and is given a form of protection, since the user can control the corpses from a distance, rather than putting their own body at risk.

Influences
Based upon the six Buddhist Paths of Reincarnation, each technique was named after one of the different "Paths": Deva, Asura, Human, Animal, Preta, and Naraka. Each of these Paths, or realms, represents one of the realms a being is reborn into after death, determined by the accumulated karma of their past lives. While the two lower Paths, Preta and Naraka, are hellish, and the two higher Paths, Deva and Asura, are heavenly, all six are considered to be Paths of suffering because they perpetuate the cycle of Reincarnation; the only way to break it and ascend to a higher state of existence is to attain enlightenment.

Trivia

 * In Naruto Shippūden: Shinobi Rumble, a technique called "Six Paths Technique" is used by Nagato's Six Paths of Pain. In this variant, Nagato generates a moderately sized sphere of debris overhead, then thrusts his arms downward, sending it crashing into the ground like a meteor. An enhanced, "Full Throttle" version of the technique called can also be performed.
