Our educational system over-stresses the importance of logical, linear and verbal skills--all of these processed primarily by the left brain. In order to advance our capabilities now, to balance ourselves and come to wholeness, we need to regenerate our innate ability to tap into the irrational, metaphorical, symbol-making, intuitive, tonal and imaginative right brain.
Although most Americans watch a lot of television and see a lot of movies, which are, indeed, image-based, most of us have been rendered passive before images. Pop culture images are predictable and put together by professionals according to formulas.
Our imaginations are stunted. And, as Einstein stated, "imagination is more important than knowledge." So, we need to reactivate and strengthen our right-brain functions and, more importantly, to simultaneously integrate those with our left-brain functions to become whole-brained, integrated beings.
