You may not fully understand the complex process that causes electricity to be generated and transmitted to your home. But you understand very well how to apply and use it to illuminate your home, power your computer, and perform hundreds of other essential tasks. The same is true of your mind. No one understands the incredibly complex workings of the brain; we know only that when we use our mind in a certain way, we achieve a desired result. If we think positively, we achieve positive results.
