Maryoku

Maryoku is the energy that enters a person through using the soul as its vessel. The amount of soul to maintain a body—and soul—hardly changes regardless of race. Maryoku refers to the amount of energy which is contained in the soul except the part that is necessary to maintain the body and soul. The amount of Maryoku also varies widely by race. It may be as large as a lake, a basin, or as small as a cup of glass. And if Maryoku is completely spent, the energy which maintains the body and soul will be insufficient and will cause fainting.
