When each thought absorbs your attention completely, it means you identify with the voice in your head. Thought then becomes invested with a sense of self. This is the ego, a mind-made "me." That mentally constructed self feels incomplete and precarious. That's why fearing and wanting are its predominant emotions and motivating forces.
Eckhart TolleYour inner purpose is an essential part of the purpose of the whole, the universe and its emerging intelligence. Your outer purpose can change over time. It varies greatly from person to person. Finding and living in alignment with the inner purpose is the foundation for fulfilling your outer purpose. It is the basis for true success.
Eckhart Tolle
