The Eight Gates are eight specific points on a person's chakra circulatory system. They limit the overall flow of chakra within a person's body. The basis for the idea of the chakra gates comes from the body's limits on the functions within it. This makes the body much weaker, but it keeps the body from expiring too soon. By opening these gates, the user can surpass their own physical limits at the cost of extreme damage to their own bodies. By using the Eight Gate Fusion technique, the user forces all eight gates open at the same time and mixes all the bursts of chakra at the same time.
The state of having all Eight Gates open is known as Eight Gates Released Formation or Eight Gates Battle Encampment (八門遁甲の陣, Hachimon Tonko no Jin). Any shinobi who activates this state will temporarily gain powers greater than a Kage. However, it is implied by opening the Death Gate, that shinobi will surely die afterwards.
