Chakra

Chakra is essential to even the most basic jutsu; it is a mixture of the physical energy present in every cell of the body and the spiritual energy gained from exercise and experience. Once mixed, it can be channeled through the chakra circulatory system, which is to chakra as the regular circulatory system is to blood, to any of the 361 chakra points (called Tenketsu) in the body. Through various methods, the most common of which is Hand Seals, the chakra can then be manipulated to create an effect that would not be possible otherwise, such as walking on water, exhaling fire or creating illusions.

By mixing different ratios of the two energies, new types of chakra can be formed. The most common product is elemental chakra, which is used to perform elemental jutsu. Most ninja have a natural affinity to one type of chakra, but they have the capacity to create elemental chakra apart from their own affinity.

Normal Chakra
Normal chakra is a form of energy all living individuals naturally produce to some degree. Contained in the "chakra coils" that mainly surround and connect to each chakra-producing organ, the energy circulates throughout the body in a network called the "chakra circulatory system " (similar to the cardiovascular system). Shinobi have learned to generate more chakra and release it outside their bodies through their "chakra points" (tenketsu ) in order to perform special techniques (jutsu). Chakra is not normally visible to the human eye, though chakra can be seen in situations where a person releases as much of their chakra as possible. This is rarely seen due to the restrictions of certain chakra points (Eight Gates), limiting the amount of chakra an individual can release at a single given time. Chakra can also be visible when doing a specific techniques (such as the Rasengan) which take a high degree of chakra control to perform. Of the many different types of techniques, ninjutsu, genjutsu, dōjutsu, and so on, all require the use of chakra. However, taijutsu is different, usually requiring no chakra use whatsoever; stamina is all that is needed. While the ninja still needs a set amount of chakra to live (i.e. life force energy), regular taijutsu doesn't require any active moulding or manipulation of chakra (with few exceptions). A standard attack like a punch or kick falls into this technique category, though chakra can always be applied to these movements to create more devastating attacks.

Chakra is the resulting form of energy when two other forms of energy are mixed together. The two energies are referred to as "physical energy" and "spiritual energy". Physical energy is collected from the body's cells and can be increased through training, stimulants, and exercise. Spiritual energy is derived from the mind's consciousness (i.e. the soul) and can be increased through studying, meditation, and experience. Having these two energies become more powerful will in-turn make the created chakra more powerful. Therefore, practicing a technique repeatedly will build-up experience, building up one's spiritual energy, and thus allowing more chakra to be created. As a result, the ninja is able to do that same technique with more power. This same cycle applies for physical energy, except this time, instead of doing things like meditation, the ninja could, say, do push-ups.

The general term for the source of chakra, the overall physical and spiritual energy an individual has, is called "total stamina". The maximum amount of chakra an individual can create and retain at a given time is called their "chakra level".

Chakra Control
Chakra takes time and a great deal of training to gradually build up. Thus, the key is not actually having chakra, but being able to sufficiently control and conserve it. Everyone has chakra, but only skilled ninja can correctly "mould" and "manipulate" it to its fullest extent. Moulding chakra involves the extraction of energies from both the body's cells and the mind's consciousness, then mixing them together within the individual. The amount of each energy will differ based on the type of technique the ninja wishes to execute. In other words, a ninja could create too much or too little chakra for a given technique, resulting in the chakra being used inefficiently. In addition, even if a ninja is able to mould the correct amount of chakra, if they cannot manipulate the chakra properly, the desired technique will not be as effective or will not execute at all. Wasting energy will also create weaknesses like early exhaustion, which would hinder the ninja's capacity to fight long-term battles. General training methods for improving one's moulding and manipulation of chakra are the Leaf Concentration, Tree Climbing , and Water Walking exercises.

As an in-between stage, some ninja can partially manipulate their chakra. This means they can use their chakra, but not effectively control it, which results in a poorly executed technique. To manipulate their chakra more easily, hand seals can be used. With these hand seals, users can control their chakra with higher efficiency, allowing them to execute their techniques more effectively. Different techniques also require the use of different hand seals.

When creating a ninjutsu, the two methods of manipulating chakra are referred to as Shape Transformation and Nature Transformation:


 * Shape Transformation deals with controlling the form, movement, and potency of chakra.


 * Nature Transformation usually deals with changing the physical properties of chakra into an element. There is also the Nature Transformation of Yin and Yang, which deals with changing the ratio of spiritual and physical energies within chakra.

These two methods can be implemented separately or together in order to create a technique. The general term for the exact moulding and proper manipulation of chakra is called "chakra control". People with skilled chakra control are usually Medical-nin or Sensor-types, both of which requires extreme control over chakra to be effective.

A good way to build up chakra in the body is to spin it into a tight spiral. Whether to spin the chakra left or right is dependent on the way the user's hair grows, either to the right or left. An opponent can negate a technique by absorbing it and reversing the spin of the chakra within their own body.
