In working on knots, I notice two layers.
First, it is the release from being blindly caught up in it. It is a release from beliefs, identifications, shoulds, and the war created by these. I find more peace with whatever is going on, I befriend it. I shift into that part of my that naturally allows it, which is myself as awareness.
Then it is the layer of accepting the gifts and harvesting the nutrients inside of it. I do this through The Work, in exploring the truths in the turnarounds of the initial belief, and then bringing these turnarounds into my daily life. I do it through voice dialog and the Big Mind process, when I investigate what the disowned voice has to offer to this human self, and how I can find a more nourishing relationship with it. I do it through Process Work, when I become the Other and that which holds both what I previously identified with and the Other. And there are innumerable other ways of finding the gifts and harvesting the nutrients inside of the knot and the (previous) disturbance.
The release is a transcending of blindly identifying with it, and the harvesting of nutrients is an active embrace of its content.
