Indeed, the great majority of human beings feel that they are alive only when they waste energy; otherwise it does not look like life.
Not to waste energy means to utilise it for the purposes for which it was given. If the energy is given for transformation, for the sublimation of the being, it must be used for that; if the energy is given to set right something that has been disorganised in the body, it must be used for that.
