This balance can be achieved by moving further out or further in on the various axis. To move outward is to respond with increased knowledge, love and service. To move back is to choose to regress toward the ego in these areas. Each of these potentialities require the others for development. Knowledge depends upon effort, a combination of volition and action.
Volition is influenced by knowledge and action and action is based upon knowledge and volition.
A love for knowledge causes gives me the motivation to work for knowledge. For my knowledge to advance, so must my love of knowledge and my activity to obtain it. If I am to accomplish something, then I need the knowledge and the volition to achieve it. If that love and knowledge are not translated into action or service, then a dangerous imbalance will occur. On the other hand, acting without love or knowledge is dangerous.
