Outer Path — Samsara of Heavenly Life Technique (外道 輪廻天生の術, Gedō — Rinne Tensei no Jutsu)
Heading: One's life is not spared for a worthy cause, life burns after it's returned from the underworld.
→ Gedo's power to return to the soul to the flesh a second time.
Six Paths technique, the antithesis to the Nakara Path, is this technique. The ruler of hades is summoned, the life of a deceased is granted life. It's different than Edo Tensei, because one is brought perfectly back to life with the body/flesh being rejuvenated, a supreme technique. Nagato had the technique in his possession and he used it to rejuvenate everyone in the Leaf village. A wondrous miracle technique, of course naturally there exists an equivalent exchange. One's life. To stake ones life, one would decisively say it's self sacrifice.
