Author: The introduction parts are mainly for those who are not familiar with the anime, Naruto. If you have watched or read the anime or manga, Naruto you may want to skip to the prologue because all of this is mainly wikipedia and origins and working of the chakra which is the basics of this story
The concept of chakra originates in Hindu texts and features in tantric and yogic traditions of Hinduism and Buddhism. Its name derives from the Sanskrit word for "wheel" or "turning" (cakraṃचक्रं[ˈtʃəkrə̃], pronounced [ˈtʃəkrə] in Hindi; Pali: cakkaचक्क, Thai: จักระ, Telugu: చక్రo, Tamil: சக்கரம், Kannada: ಚಕ್ರ, Chinese: 轮, Tibetan: འཁོར་ལོ་; khorlo).[1]
The chakras are believed to be a number of wheel-like vortices which, according to traditional Indian medicine, exist in the surface of the subtle body of living beings. The chakras are said to be "force centers" or whorls of energy permeating, from a point on the physical body, the layers of the subtle bodies in an ever-increasing fan-shaped formation. Rotating vortices of subtle matter, they are considered focal points for the reception and transmission of energies. Different belief systems posit a varying number of chakras; the best-known system in the West has seven chakras.
Although there are various interpretations as to what exactly a chakra is, the following features are common to all systems:It is typical for chakras to be depicted as either flower-like or wheel-like. In the former case, "petals" are shown around the perimeter of a circle. In the latter, spokes divide the circle into segments making the chakra resemble a wheel (or "chakra"). Each chakra possesses a specific number of segments or petals.
They form part of a subtle energy body, along with the energy channels, or nadis (Thai: นาฑีส์), and the subtle winds, or pranas (Thai: ปราณส์).
They are located along a central nadi, Sushumna (Thai: สุษุมฺนา), which runs either alongside or inside the spine.
Two other nadis, Ida (Thai: อิทะ) and Pingala (Thai: ปิงฺคละ), also run through the chakras, and alongside Sushumna. They occasionally cross Sushumna at the location of the chakras.
They possess a number of 'petals' or 'spokes'. In some traditions, such as the Tibetan, these spokes branch off into the thousands of nadis that run throughout the human body.
They are generally associated with a mantra seed-syllable, and often with a variety of colours and deities.
A chakra is believed to be a center of activity that receives, assimilates, and expresses life force energy. The word chakra literally translates as wheel or disk and refers to a spinning sphere of bioenergetic activity emanating from the major nerveganglia branching forward from the spinal column. Generally, six of these wheels are described, stacked in a column of energy that spans from the base of the spine to the middle of the forehead, the seventh lying beyond the physical world. It is the six major chakras that correlate with basic states of consciousness...
Once moulded, it can be channelled through the chakra circulatory system, which is to chakra as the regular circulatory system is to blood, to any of the 361 chakra points 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.
Most warriors have a natural affinity to one type of chakra, but they have the capacity to create elemental chakra apart from their own affinity. There are five basic types, each stronger and weaker to another, but their relations, weaknesses, and strengths to each other are all explored. For instance, Fire is weaker against water but stronger against life. It matches Death equally while all others fall weaker to death except life which is stronger to death. Wind style chakra is weak against lightning style.
Chakras are described as energy centers along the spine located at major branchings of the human nervous system, beginning at the base of the spinal column and moving upward to the top of the skull, through which, believers assert, pass 3 major energy channels, Sushumna, Ida and Pingala. Chakras are considered to be a point or nexus of biophysicalenergy or prana of the human body. Shumsky asserts that "prana is the basic component of your subtle body, your energy field, and the entire chakra system...the key to life and source of energy in the universe."Each chakra in your spinal column is believed to influence or even govern bodily functions near its region of the spine. Because autopsies do not reveal chakras, most people think they are a fancy of fertile imagination. Yet their existence is well documented in the traditions of the Far East...
There is also the dealing of Yin and Yang and the balance of mental and physical energies. In addition to these five elements, certain kekkei genkai can mix elemental chakra to form new natures, for example it is possible to mix water and wind into ice. While many ninja can use more than one type of chakra, very few are able to use them simultaneously.
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 warriors can correctly "mould" and "manipulate" it to its fullest extent.
