When we hear the term "solar powered" we are likely to think of devices like calculators, watches and cell phones that recharge using solar energy.  Perhaps even cars will be solar powered in a few years.  But does anyone ever think of humans when the talk of solar power?  Usually not, but, in truth, we are very much solar powered.  
    We are directly solar powered because energy from the sun heats us and our world.  We need energy from the sun to make vitamin D.  We need light from the sun in order to see.  Other frequencies of energy from the sun affect us in other ways.
    Indirectly, we are solar powered as well.  We eat plants that need heat and light from the sun to grow.  We eat meat from animals that also eat plants so they are indirectly solar powered and also directly solar powered for heat and other things.  Recent studies have shown that people who hide from the sun to prevent skin cancer only end up causing other health problems due to a lack of solar energy.
    What about out spirit?  Is it solar powered also?  Absolutely.  Our spirit and soul needs energy to survive and grow just as our physical body does.  The difference is that the spirit and soul need the energy from the spiritual sun rather than the energy of the physical sun.
