In fact, that ability to say "I don't know" can take years to learn. But when you know that you don't know, you become ready to learn. And I would say that learning is part of healing; it is when we discover what we were doing wrong, and how to do better. This learning is the process of growing up.
Here are the 2 true things:
1. You are the foremost authority on yourself. Nobody knows more about you than you do. You are the only one who can feel what it feels like to be you on the inside.
2. There are things about you that others can see, and you cannot. This is part of the human condition. Even when we are provided with a mirror, we can avoid looking into it. We might avoid people who will tell us things about ourselves that we do not want to believe.
I interact often with people who want to self treat for what ails them. They look it up on the internet. They study the herbs or remedies and pick what they think will help them. Sometimes they do pretty well.
More often, people fail in their attempts to self-treat because of #2. The reason why they are unwell is something that they are unconscious of, or in denial about. When this is the case, there is no replacement for seeking help.
I see this so much that I am redirecting my practice toward helping people with this process. It is a shift toward energy medicine, toward spirituality, and away from science and evidence basis. I understand things about people from being with them. I know things from what they say, and what they don't say. And I have neglected this part of my practice.
From this day forward I dedicate my practice to helping people, myself included, to see into the blind spots and dark corners of our psyches. From this day forward I dedicate my practice to bringing us all home to a spiritual center where we can begin to integrate all the parts of ourselves, and recover true health.
