When a thought or your experience impacts the conscious mind, the energy begins to move throughout the mind and body, attaching to every energy that already exists. This means that if a thought or experience provokes anger in you, it will find and connect itself to every thought or experience that ever has caused you to feel this way. Whether your first experience was at age three, four, five or sixteen does not matter. The energy of the thought and experience remains in your subconscious mind.
To bring back our balance, this energy or emotion has to be experienced, processed and let go.
This is where EFT comes. It dissolves blocked energy (unprocessed emotions) and restores the natural and balanced flow and movement of energy.
