In most cases, the cause of sleep disorder is not environmental disturbance, but rather internal disturbance (the stuff going on in your mind). In particular, the ability to fall asleep quickly and sleep deeply is tied to your mental condition just before and during sleep. And while a major purpose of sleep is mental and physical renewal, the degree to which we receive that benefit is greatly increased if we develop a pre-sleep mindset where our body's natural ability to renew itself is maximized. After you begin using the techniques taught in the MC² Method, you'll find yourself able to effortlessly cultivate just such an internal environment.
