Daizenshuu 7: Ki...
"The comprehensive power an individual has, like Battle Power, life force, and the like. Used primarily with a nuance that indicates Battle Power, you could say that the higher a person's ki is, the stronger they are. A boosted ki emanates from the body like an aura. It cannot be seen by eyes, but proficient warriors are able feel it."
