The conscious brain can only work with what it already knows. This is the strength of experience. When we seek solutions to probems we automatically search our memories, our experience banks, for answers based on what has worked in the past. It is only when we realise that none of the old solutions are working that we finally step into a place of 'not knowing'.
Many of us have inevested our lives and careers in knowing the answer and finding solutions so this place of not knowing is somewhere that is profoundly uncomfortable to us. To own it feels like failure. But it is when we can truly admit that we do not know the asnwer, that we do not have the solution, and embrace that place that the Universe can step in and begin to create something new with us because we have stopped getting in the way with our solutions that do not work.
Embracing not knowing is an act of power.
