Outside of the four psychological functions, we need to consider that the body has a kind of intelligence that is worth getting acquainted with.
When I was in Somatic Experiencing, my therapist pointed out loud every time I changed positions or when my breathing was altered. She also asked me to locate emotions or discomfort in my body, as well as noticing the difference between how the left leg felt compared to how the right leg felt for instance.
It’s clear to me that the body intelligently reacts to language, thoughts, attitudes, and will betray you when you are out of your depth. A common issue I have noticed is me shaking my head left to right (as if I was saying no) when talking to someone. As soon as I notice this happening, I reconsider what I am saying as my body seems to disagree with the words I am using. Other times, hearing some people talking causes a kind of light buzz around my skin, which I have read described as the experience of cellular memory.
There are two more centers of the body that should be talked about: the gut and the heart. In my understanding, the gut is responsible for all instinctive decisions, whereas the heart is a mediator between many contradictory impulses.
Similar to other body responses described above, I value instinctive reactions more than any intellectual decisions. Thus, I never ignore gut instincts when they happen. Similarly, I put a lot of emphasis on observing my heart responses: if I feel my heart sinks down or feels constricted when I approach a topic or an event, I know something is off. On the other hand, if my heart feels like it’s opening or brightening up, I assume that I can safely rely on its discernment.
I have gone fairly quickly about all these concepts because I am no expert at this. The main takeaway I would like the reader to keep is that one should include body responses, gut instincts, and heart reactions into their thinking. This is what I mean by mind-body-heart negotiation.
If you want to read more about this, I can only recommend a few books.
