Senjutsu

Diagram of Spiritual,Physical, and Natural energies combining to create Senjutsu

Senjustu (仙術, "Sage Jutsu","Sage Techniques") is a special ability only for those who are practitioners to learn how to draw the energy of nature inside of there bodies blending it with their own chakra and with combining the Spiritual Energy ( or Mental energy) and there Physical energies. Which gains the user the field of jutsu that allows the user to sense and gather the natural energy (自然 エネルギー, Shizen Enerugī) surrounding the field to use to your advantage. Senjutsu specialists can make this energy penetrate and combine them with their own creating a new and powerful chakra called "Senjutsu Chakra" (仙術 チャクラ, Senjutsu Chakura). This chakra type allows the user to enter a new state called the "Sage Mode", which can dramatically increase the strength of all ninjutsu, genjutsu and taijutsu and can increase the physical body and speed times two. A person who is able to use Senjutsu is called a Sage (仙人, Sennin). Senjutsu chakra cannot be used by those untrained in senjutsu, meaning a shinobi who doesn’t know the proper stages of senjustu can’t learn Sage Mode and its complete enhances.

Locations To Learn Senjustu

It seems that there are only two ways to learn Senjutsu.

1. Is to learn under the Tutelage of Mt. Myoboku with the toads Shima and Fukasaku who trained Naruto Uzumaki and his sensei Jiraiya.

2. The world of snakes Ryuichi Cavern, where Kabuto learned of White Snake, which allowed you to change your snake skin that of a dragon.

During The Fight With Obito and Madara

The Shinju 3rd jinchuriki Obito Uchiha gained the ability to nullify only normal and some advance Ninjutsu, but had later discovered he could not nullify techniques augmented by senjutsu unlike his once known comrade in battle Madara who became the Shinju next jinchuriki. Had no problems with Augmented Senjustu attacks since he obtained Senjustu already from his rival Hashirama Senju.
