We all know the proverb, "as a man thinks in his heart so is he." Our hearts connect our spiritual and psychological domains because scientists revealed unto us that our hearts possess a brain referred to as the heart and brain connection.
The heart and brain connection consists of a two-way communication between the cranial brain and the heart. There are 4 types of communication between the two: neurological (nervous system), biophysical (pulse wave), biochemical (hormones), and energetic (electromagnetic fields). Our hearts' brains consist of our authentic thoughts that we hold about ourselves. Our former education taught us that our brains hold the thoughts we possess about ourselves.
Our focus should be to shift any negative thoughts about ourselves to positive ones. When we learn to sustain heart-focused positive feeling states, the brain can be brought into entrainment with the heart. This entrainment creates balance and harmony. In addition, heart-focused positive feeling states free us to be and live our authentic selves every day.
