Some say that this personal transformational change is like peeling the layers of an onion. Maybe that might be because it can cause you to cry (LOL) a lot but we like to think of it in terms of peeling back the layers of our being. As we learn more and more about ourselves and move through stored issues and stories we have held, we start to peel back the layers only to reveal the true essence of who we are. The Self has a lot of layers, just like an onion, and we can be more complicated than we appear to be.
One layer that is hard to peel is the layer of judgment. Judgment causes most of our suffering. We constantly are judging something as good or bad, right or wrong, like or not like, and depending on how we judge it we either feel pain or pleasure. It is probably the hardest layer to peel, because it is the basis of who we are and how we perceive the world. If we let go of judgment and try to become just a witness to the moment. Just watch, not judge. When we can do this, we can reduce suffering and may find peace.
Peeling the onion is a perfect metaphor for a spiritual journey. When we let go of who we think we are, there is nothing left but the divine.
