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.

Had no problems with Augmented Senjustu attacks since he obtained Senjustu already from his rival Hashirama Senju.
