I think by now, everyone knows the importance of energy for our physical well being.  We see ads all the time for Redbull, 5 hour energy and other energy boosters.  Body builders especially take various suppliments to boost energy because they know they can't get a good workout if they lack energy and they can't grow big muscles if they can't have good workouts.
    The same is true for our spiritual side.  Our spirit and soul need energy.  They need energy to grow, to get strong, and to develop your spiritual side until you reach that ultimate stage of spiritual development known as Christ Conciousness.  And, as I have said before, the source of the energy that nourishes and strengthens the spirit and soul is God's Light which comes to us primarily from the spiritual sun.

Any star or sun is a focal point of energy exchange.  This means that where there is physical energy, there is spiritual energy. ~Gene Savoy
