If you struggle with self-worth, affirmations and working with the energy of your chakras can be really powerful. Evidence-based research shows that affirmations actually change the brain on a cellular level—in other words, what you think about matters—a lot. “Thoughts have a direct connection to your health,” says Dr. Joseph Dispenza, author of Physics, the Brain and Your Reality “Thoughts make a chemical. If you have happy thoughts, then you’re producing chemicals that make you feel happy. Negative, angry thoughts and fearful thoughts also produce chemicals to make you feel how you’re thinking.” Neurons connect in your brain by attaching to thoughts and memories. Thoughts then become organized into a “pattern” or “neuro-net”. For example: The feeling of love is stored in a very large neuro-net. Each person builds his/her concept of love from many different ideas and experiences.
