One extremely important purpose of emotions from an evolutionary perspective is to help us decide what to remember and what to forget. The cavewoman who could remember which cave had the gentle guy who gave her food is more likely to be our foremother than the cave woman who confused it with the cave that held the killer bear. The emotion of love (or something resembling it) and the emotion of fear would help secure her memories.

The way our brain is wired, we only see what we believe is possible. We match patterns that already exist within ourselves through conditioning.

Your mind is in every cell of your body.

My research has shown me that when emotions are expressed-which is to say that the biochemicals that are the substrate of emotion are flowing freely-all systems are united and made whole. When emotions are repressed, denied, not allowed to be whatever they may be, our network pathways get blocked, stopping the flow of the vital feel-good, unifying chemicals that run both our biology and our behavior.

I'm a scientist. We don't talk about the spirit. Soul is a four letter word in our tradition.

Most psychologists treat the mind as disembodied, a phenomenon with little or no connection to the physical body. Conversely, physicians treat the body with no regard to the mind or the emotions. But the body and mind are not separate, and we cannot treat one without the other.

Part of being a helathy person is being well integrated and at peace.
