How can new choices change biology?

Dr. Joe Dispenza discusses how making new choices can profoundly affect our biology. He explains that if we continue to feel emotions connected to our past, our neurocircuitry, neurochemistry, hormones, and gene expression remain unchanged. However, he experimented with novice meditators who, within just seven days of making new choices and experiencing new emotions, saw significant changes in their biology. These changes were not minor but were major transformations in gene expression across diverse individuals, illustrating a collective shift in biology due to new choices and experiences 1.
