" The key to thriving is to help these parts work well together—to integrate them. Integration takes the distinct parts of your brain and helps them work together as a whole. It’s similar to what happens in the body, which has different organs to perform different jobs: the lungs breathe air, the heart pumps blood, the stomach digests food. For the body to be healthy, these organs all need to be integrated. In other words, they each need to do their individual job while also working together as a whole. Integration is simply that: linking different elements together to make a well-functioning whole. Just as with the healthy functioning of the body, your brain can’t perform at its best unless its different parts work together in a coordinated and balanced way. "
