We can see only a tiny fraction of the amount of light available. There is a whole spectrum of ultraviolet and infrared light that is much greater than the visible spectrum that is vitally important to life, but we cannot see it. Of course anyone who's ever been to the beach knows that you ignore the ultraviolet spectrum to your own pain and discomfort later on. These spectra, though invisible to us, are profoundly important to our life, health and emotional well being, just ask anyone who gets depressed during the wintertime. Similarly, there is a whole spiritual world we cannot see that is beyond the limits of our physical senses that is just as important, if not more so, and impacts our lives in ways we do not fully comprehend and to which most of us are oblivious. We are no physical beings having a spiritual experience, we are spiritual beings have a momentary physical experience. Learn to sense this other world, look for signs of its impact every day and learn its power and purposes.   http://www.slideshare.net/steve4040/the-spiritual-spectrum-82315
