You are cut off from Being as long as your mind takes up all your attention. When this happens—and it happens continuously for most people—you are not in your body. The mind absorbs all your consciousness and transforms it into mind stuff. You cannot stop thinking. Compulsive thinking has become a collective disease. Your whole sense of who you are is then derived from mind activity. Your identity, as it is no longer rooted in Being, becomes a vulnerable and ever-needy mental construct, which creates fear as the predominant underlying emotion. The one thing that truly matters is then missing from your life: awareness of your deeper self—your invisible and indestructible reality.
— Eckhart Tolle
