The groundwork was laid for paradigm expanding concepts of quantum physics by a mystical messenger named Albert Einstein. There are several quotes that I use on the page facing the copyright page in the beginning of my book that come from individuals whom I consider to be mystical messengers.
This quote from Mark Twain speaks to the reality of human internal dynamics that I keep repeating throughout my writing. Our intellectual paradigm - mental attitudes, definitions, and beliefs - determine our perspectives and expectations, which in turn dictate our relationships and emotional reactions. If our intellectual paradigm is limited - if we cannot imagine a larger perspective of life - than what we perceive is limited, is out of focus. If we cannot use our imagination to open up to different interpretations of what we are seeing, then we are wearing blinders and can only see a limited view.
As an example: A traditional therapist / psychologist / psychiatrist has a limited perspective that restricts them to labeling behaviors - that are symptomatic manifestations of codependency in my belief - in such a way that they fit into the boxes their intellectual paradigm dictates. A Freudian will twist everything to fit into the second chakra perspective that Freud was viewing life from. A Jungian will come from more of a heart chakra centered point of view because Carl Jung reached that level of consciousness - but even then emotions are usually discounted. Someone who believes that brain chemistry is the higher power in determining emotional health will look for chemical solutions.
