If you're interested in the science behind thinking, being, and doing, there's an interesting series on Gaia called "Rewiring the brain" by Joe Dispenza. 

It's not an easy watch for someone like me who was never cared much for science or biology at school. A full season of Star Trek Discovery in a week? Sure! Episode 1 of Rewiring the brain? Two months.  https://www.gaia.com/video/introduction-your-brain

Why I've persisted is because I know it holds the key to why my New Years' resolutions don't last beyond the new year. From an ego perspective, a scientific reason is way more comforting than the general "lack of self-discipline" and "self-limiting beliefs" that are such downers on one's road to self-actualisation.

So here goes my bare-bones understanding of the link between the brain and our intentions. (Neuroscientists, please step in!)

According to Joe Dispenza, we should consider our brain as three separate brains each with different functions that take us from thinking to doing to being.

1. The frontal lobe is the "thinking" brain.

This is the part of the brain responsible for thought, such as decisions, intentions, and attention. This is where we store information and what we know.  But what's the use of knowing if we do nothing with the knowledge? We need to act. We need to create new experiences. If we don't create new experiences, our thoughts become nothing more than decisions, intentions, and attention.

2. The limbic brain is the "doing" brain.

When we can get our minds and our bodies working together, we create an experience. For example, exercising instead of just knowing that we need to exercise.

As we experience, our limbic brain begins to produce a chemical we know as a feeling or emotion. The more we experience the same feeling, the more we are programming our bodies to believe what our brain already knows. It becomes a habit with less thinking and more doing. We are rewiring our brains.

The limbic brain is also the seat of your autonomic nervous system, which is the part of the brain that subconsciously regulates hormone levels, sugar levels, temperature and so on. When we "do" something enough times, it becomes a subconscious process where we know we do it, but we don't know how we do it. We're beginning to master it.

3. The cerebellum is the "being" part of the brain.

The cerebellum is the part of the brain where we begin to develop implicit memories. It's where we've done something so many times that we no longer have to consciously think about it. It's who we are.

Herein lies the key...

According to Dispenza:  "The moment you feel unlimited; the moment you feel abundant; the moment you feel free from any experience, now you are teaching your body chemically to understand what your mind has intellectually understood."

It's all about getting into flow.

When we're consistently operating in flow—when we're constantly experiencing the natural high of tapping into our inner genius, prioritising our passions, or pursuing our purpose—we are rewiring our brains. We are teaching our bodies to understand what our minds already intellectually know. 

If we do it enough times, it becomes part of who we are without even having to think about it. We then have no choice but to become the people we're fully meant to be... unlimited, abundant, and free.
