The ego is not only the unobserved mind, the voice in the head which pretends to be you, but also the unobserved emotions that are the body's reaction to what the voice in the head is saying.
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 TolleNeither God nor Being nor any other word can define or explain the ineffable reality behind the word, so the only important question is whether the word is a help or a hindrance in enabling you to experience That toward which it points.
Eckhart TolleWith the egoic consciousness having become so dysfunctional, and now having at our disposal all these enormous technologies and scientific advances, if nothing changes the ego will use those things - as it already has been doing - and will amplify the technology that we now have. The scientific advances, to a large extent, will be used in the service of the ego, and they will become more and more destructive.
