In your present, individual state of consciousness we identify with the thoughts and emotions that appear in our mind, so we believe that we are a separate, illusionary person, an Ego. A lot of us are not satisfied with what we are, and we would like to have a better and more beautiful personal history. That is why we create a mental image of our desired personal development, and the ways of making the work of our Minds more effective.
In order to achieve the mental image we ourselves have created, we embark on a foolish game, as we attempt to bring our Minds under our own control, and be the masters of our own development. Since we do not know the nature of the Mind, this venture is destined to failure right from the beginning.
