Affirmations play a major role in breaking the negative thinking patterns not only from the conscious mind but also from the subconscious mind. Affirming a positive thought with positive emotion imprints in your memory. When this process is done on a daily basis for a prolonged time of more than 90 days, it creates a neural pathway in your brain. This is also known as muscle memory. Affirmations work powerfully by creating muscle memory. When you practice positive affirmations daily, you are in a way developing positive muscle memory which stays with you life long.
