Mushin

Mushin (無心, No Mind) is a state in which extremely skilled warriors adopt within combat, albeit it is often nameless. Achieving this state often places said warrior to a status equivalent to a legend, irrespective of the discipline by which they achieve it.

Description
Mushin is not a technique, but rather, a state a truly skilled warrior may enter whenever he enters combat. It is upon continuously training the mind, body and soul and harmonizing the purpose of all three aspects of a warrior's being that this state is possible to achieve. In simple terms, Mushin is the abandonment of thought within combat, and one's focus shifts from the material world to one's subconscious world. In doing so, the entirety of their being aligns with every action undertaken, for it is lead by an unfettered subconscious.

Through observations by many warriors, Mushin's technical basis was found beyond its philosophical meaning: it is the connection of one's and physical nervous system. Through continuous, cyclic chakra flow across the entirety of the body (albeit without unlocking the ) one's chakra network is able to temporarily act as an extension of one's nervous system. In doing so, the chakra then exerted from the individual, often represented by a slight aura and glowing of the eyes, is something akin to a sixth sense that is directly connected to the subconsciousness of the warrior.

The connection of chakra to one's body with alignment to the individual's subconscious is the reason for how the mind, body and soul of a warrior are able to be aligned within the Mushin. In doing so, their reaction time and skills are unimpeded by conscious thoughts. As a result, the very idea of technique becomes useless to a warrior of this level of skill, for they can seamlessly perform any technique that is retained within their subconscious and use it in the most appropriate situation, all with an incredible boost to their combat prowess.
