The philosopher Descartes believed he had found the most fundamental truth when he made his famous statement: "I think, therefore I am." He had, in fact, given expression to the most basic error: to equate thinking with Being and identity with thinking. The compulsive thinker, which means almost everyone, lives in a state of apparent separateness, in an insanely complex world of continuous problems and conflict, a world that reflects the ever-increasing fragmentation of the mind.
Eckhart TolleIf it is the quality of your consciousness at this moment that determines the future, then what is it that determines the quality of your consciousness? Your degree of presence. So the only place where true change can occur and where the past can be dissolved is the Now.
Eckhart TolleJust watching an animal closely can take you out of your mind and bring you into the present moment, which is where the animal lives all the time - surrendered to life.
