Thinking is a wonderful tool if it's applied. Thinking, however, can not become the master. Thinking is a very bad master. If you're dominated by thinking then your life becomes very restricted.
Eckhart TolleDifferent ages have certain approaches, which may be more effective for one age and no longer effective in another age. The world that we live in now has much greater density to it; it is much more all-pervasive. And when I say "world," I include the human mind in it. The human mind has grown even since the time of the Buddha, 2,500 years ago. The human mind is more noisy and more all-pervasive, and the egos are bigger.
Eckhart TolleAfter having been lost in the world, suddenly, through the pressure of suffering, the realization comes that the answers may not be found out there in worldly attainment and in the future. That's an important point for many people to reach. That sense of deep crisis-when the world as they have known it, and the sense of self that they have known that is identified with the world, become meaningless.
Eckhart TolleSo the single most vital step on your journey toward enlightenment is this: learn to disidentify from your mind. Every time you create a gap in the stream of mind, the light of your consciousness grows stronger. One day you may catch yourself smiling at the voice in your head, as you would smile at the antics of a child. This means that you no longer take the content of your mind all that seriously, as your sense of self does not depend on it.
