I don't think we can fully quantify any form of energy whether it exists in the physical, mental or spiritual dimensions of existance. We try to make discoveries and those carry us through until we find better ones but the whole energy concept is complex. I don't think I focus too much on any side of the dimensions of existance. All three are extremely important. I always try to speak and write about our physical reality when am talking about mysticism because it is an area that most people want to ignore or think is inferior to the spiritual or mental forms of energy. If this article seems to focus to much on the physical, it is because I want people to relate their day to day experiences to a bigger picture of our life experience to help them live a better life ahead...
