Inner Path (Sigma)

 (ないたいまが, Naitai Maga) is the ability granted to the wielder of Sigma Uchiha's Rinnegan to connect with one's inner self. Sigma said it focuses on his ability to rebirth himself. Sigma uses the Naidō Art: Samsara of a New Spirit Technique, to rebirth himself allowing himself to replenish. His old spirit, would be stored into the King of Hell where it would be replenished or he could use in his Outer Path, to give people their own spirit back. Sigma is too seen to enter his conscious, where he is alone with himself, even depriving connections to both Omega Sigma X, and the Datara. Sigma is then able to purify his chairs so that it is cleansed and pure.

During a time period, Sigma learned that the Inner Path exceeded past the persons' normal self, showing them things they wouldn't see on their own. The inner path allows Sigma to bypass the deceiving tongue of his opponents, making him immune to their venom. Granting him the ability to look into himself to find his truth. Sigma has currently shared that the inner path is much like gathering, to enter Sage Mode. But instead of gathering energy, he's just purifying his own. A person who enters the Inner Path, gains unique markings upon their face.

It is said that Spirit was born from the inner Sigma, creating speculations that Sigma was destined to awaken the Rinnegan.
