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 TolleWhatever you accept completely will take you to peace, including the acceptance that you cannot accept, that you are in resistance.
Eckhart TolleThe story of the Zen Master whose only response was always "Is that so?" shows the good that comes through inner nonresistance to events, that is to say, being at one with what happens. The story of the man whose comment was invariably a laconic "Maybe" illustrates the wisdom of nonjudgment, and the story of the ring points to the fact of impermanence which, when recognized, leads to nonattachment. Nonresistance, nonjudgement, and nonattachment are the three aspects of true freedom and enlightened living.
