Do I need to understand why and what I fear? Or is just staying with it enough to release it?
It is enough to consciously be with the feelings in the body that accompany the fear. That simple, open awareness has within it all the intelligence and purpose to heal and release the fear. If it is important to understand the history and causes behind the fear for a complete release, then that understanding will present itself as flashes of insight and realization.
