Thinking, or more precisely identification with thinking, gives rise to and maintains the ego, which, in our Western society in particular, is out of control. It believes it is real and tries hard to maintain its supremacy. Negative states of mind, such as anger, resentment, fear, envy, and jealousy, are products of the ego.
Eckhart TolleWhen you are present, when your attention is fully in the Now, Presence will flow into and transform what you do. There will be a quality and power in it. You are present when what you are doing is not primarily a means to an end (money, prestige, winning) but fulfilling in itself, when there is joy and aliveness in what you do.
Eckhart TolleWhereas the notion of purpose before was always associated with future, there is now a deeper purpose that can only be found in the present, through denial of time.
Eckhart Tolle
