What is chakra? And what is JutSu?

Chakra or known as chakura is a 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. There are 3 type of jutsu.

1st Genjutsu

Genjutsu or known Illusionary Techniques are techniques that are employed in the same fashion as ninjutsu, requiring chakra and hand seals. However, the primary difference between the two (ninjutsu and taijutsu) is that the effects of genjutsu are illusory; instead of attacking the victim's body, genjutsu techniques manipulate the flow of chakra in the victim's brain, thus causing a disruption in their senses.

This is often used to create false images or to cause pain from trauma (because the body is led to believe it is in pain). However, there are plenty of other uses depending on the situation. Normally the use genjutsu to extract information from enemies and gain knowledge about enemy strategy and hideout. They are not used as often as ninjutsu because they don't physically harm the opponent.

2nd Ninjutsu

Ninjutsu or known as Ninja Techniques refers to any technique that utilizes chakra and allows the user to perform actions that a normal person otherwise would be incapable of doing. Unlike genjutsu, which causes the opponent to experience illusions, the effects of ninjutsu are real. Ninjutsu relies on chakra and, most of the time, hand seals to be effective. The hands are put in sequential positions that molds and manipulates chakra in the necessary manner to perform a jutsu. This is not always needed, however, and some jutsu become second nature to experienced ninja, after which they can perform them at will.

3rd Taijutsu

Taijutsu or known as Body Techniques is a basic form of jutsu that typically does not require chakra, but chakra may be used to enhance techniques. Taijutsu generally require no hand seals to perform and are much quicker to use than ninjutsu or genjutsu. Taijutsu is simply put, hand-to-hand combat.
