Natural Energy

, is energy that can be collected from the atmosphere and terrain. If one can collect the natural energy from around them and combine and balance it with the spiritual and physical energy that makes up their chakra, they can become sages and enter the Sage Mode, allowing them to use senjutsu. This method can be taught by the inhabitants in one of two legendary locations:



The people of Jūgo's clan, had special bodies that were capable of drawing in natural energy, but are unable to control it, thus causing them to randomly go berserk. Orochimaru also figured out how to draw in natural energy thanks to Jūgo, but was also unable to use it properly, since he didn't possess the right body or receive training in the arts of senjutsu.

There is also an anime-only technique of drawing upon natural energy, and then releasing it in a devastating attack developed by the Tsuchigumo clan.
