The Eight Gates are eight specific tenketsu on a person's Chakra Pathway 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 undergoing intense training, one can learn how to open these gates allowing the user to surpass their own physical limits at the cost of extreme damage to their own body.
