Ego is neither positive nor negative. Those are simply concepts that create more boundaries. Ego is just ego, and the disaster of it all is that you, as a spiritual seeker, have been conditioned to think of the ego as bad, as an enemy, as something to be destroyed. This simply strengthens the ego. In fact, such conclusions arise from the ego itself. Pay no attention to them. Don't go to war with yourself; simply inquire into who you are.
The unknown, our own true nature, has the capacity to wake itself up when you start to fall in love with letting go of all the mental structures you hold onto. Contemplate this: there is no such thing as a true belief.
Go ahead, climb up onto the velvet top of the highest stakes table. Place yourself as the bet. Look God in the eyes and finally, for once in your life, lose.
We can't have an idea of what life should look like, about how spirit should be manifesting as our very life, because all of those ideas would just be products of the past - something we learned, imagined, or desired. Once again, we find ourselves back in the unknown - not in the idea of the unknown, but in the lived reality of it. It's the mind humbled, on its knees, with bare feet and free of the known.
