Could awarness of the now make humans content and end all aggressions on the planet?

Do you believe that your mind is you like in the famous statement: I think therefore I am (Descartes)? Or is this just an unconscious state of being, a zombie state that most humans on planet earth live? What if there was another dimension of us that did not live in the past (the already passed dead) or the future (nonexistent, did not happen yet)? A dimension of us, always aware of the instant of now – sometimes called the “observer” for which the past and the present mean nothing. Most of us lives our life’s in pain inflicted by “bad” memories of passed times or on hopes to reach the end of the rainbow completely blind for the moment in which we are. What is this my enigmatic fuzz about? I have been practicing Zen for many years, now having a break as many do, when life and mind takes control. Recently I stumbled over a book, one of those best sellers: “the power of now” by Eckhart Tolle, a non-religious “tale” about awareness of that precious moment that we all live but are ignorant of or blind to. I found no contradiction to my own wisdom of Zen but a slightly different way of looking at the issue of the interior of one self, of one-ness, a great complementing teaching about how to come to peace with myself.

Now it is time for a small tale: The insightful being and “scientist” Carl Jung tells in of his books of a conversation he had with a native American chief who pointed out to him that in his perspective most white people have tense faces, staring eyes and cruel demeanor. He said: “They are always seeking something. What are they seeking? The whites always want something. They are always uneasy and restless. We don’t know what they want. We think they are mad.”

I think this still holds for a pretty good description of us people in western style regions. We are always looking for greener grass or filled up with anxiety or fear even though we know that our time is limited here.

Could we be content without a continous wanting of new possessions, without being held back and crippled by attachments, without always thinking about coming to and end?
