Increasing your awareness acts as the thawing agent. When you practice paying attention to sensations, limitations, and the quality of your actions, it's like you are applying warmth to the frozen habits.
The Feldenkrais Method often involves gentle, mindful exploration of movement. As you engage in these exploratory movements, they start to "melt" the rigidity of their habits. This process involves organically and systematically taking apart the frozen, habitual patterns by introducing new, conscious and effective ways of moving.
The brain's neuroplasticity comes into play. Neuroplasticity refers to the brain's ability to reorganize itself based on experience. As you bring awareness to your movements, you create new neural connections and pathways, gradually reshaping the way the nervous system coordinates and executes those movements.
