What does charkas mean?

Answer 1

the basic energy source necessary for ninja in Naruto to perform most jutsu. Ninja produce chakra through the combination of their two energies: the physical energy, drawn from the trillions of cells that make up the human body, and the mental energy, gained through experience and by training the body. Once created, chakra moves throughout the body in a manner similar to the circulatory system and is delivered to one of 361 chakra release points. By performing a sequence composed of any of twelve different hand seals, chakra can then be manipulated to create supernatural effects, such as walking on water.
