The idea of 'me' is an imposter. It's not the real you. It's a notion that I am this body. It's a notion that I am here in the world, that I am something distinct and separate from the rest of the world. But that's not true.
You are not separate from the world. It's a flawed idea. How? Well, there's no distinct point where the body ends and the rest of the world begins. We may casually see the tips of the fingers and believe that is where that part of the body ends. We may feel the feet as they touch a soft carpet, walk on grass, or slide on some socks. There is a sense of where the feet end and where the rest of the world begins. But it's not strictly correct.
There may seem to be a firm outer layer to the body that we call skin, but the skin isn't permanent. It is continually changing. It is continually replaced as the outer layer joins the environment. The skin is continually flaking away from the layer that seems to separate the body from the world, and then it is no longer the body. We could say that the outer layer of the body is continually replaced as it becomes "not the body".
So what seems to be a defining layer where the body is separate from the rest of the world is really indefinite. Really nothing is separate from the world. The world is always whole and complete. It is the mind that has the idea of separation and division. It is the mind that labels this and that as separate parts of an indivisible world.
What do we do about this? We recognise that the ideas of me that have shaped human life are flawed, and we allow this clearer understanding to permeate through the human world. Who can be our enemy when there is really no separation? Why should we argue and fight when truly we are one? This recognition breaks down the barriers that the human psyche has formed. These mental barriers seem to prevent us from being naturally as we are, at peace and at one.
Of course, really there is no 'us'. There is no real me and you. It is one infinite indivisible Being appearing as many. The peace and Oneness of Being remains timelessly as it is, whilst appearing to be and not to be.
