Most of us are under the illusion that consciousness is localised inside the body or the brain or behind your eyes . But that's just simply an illusion. If you study your direct experience carefully enough ..you will realize that consciousness extends to the whole bubble of perceptions that you are experiencing right now .the problem is you identify yourself with your physical body .which is only a small portion of the entire experience. You are the entire experience that you are experiencing right now. So if you're experiencing seeing a tree over there ..you are the tree ..consciousness is localised in the tree itself not in your eyes .you don’t actually see the tree with your eyes ..you see the tree exactly in the place which it is occurring in .  what you think is the world out there is actually you. The problem is you think there is me here and a world there and me is looking at the world. That's duality. The observer is the observed. And this is meant literally. What you think is a screen right now that is being perceived by you via a medium of perception system (eyes) is actually what you are. You are not looking at the screen right now. You are the screen. And this is the case for any other duality. You and your thoughts are actually one thing. You and your feelings are actually one thing. Meaning there is no you that is feeling feelings.. The feelings are what you are. Evident by when there are no feelings there are no feeler as well. Similarly when there is no perceiver there are no perceptions.  And since there is in fact no duality between the perceiver and the perceived.. There is neither a you nor a world out there.. There is one unbroken actuality. And this is it. In this actuality there is actually no "you" and no "other". If you try to pin point where or what exactly is" you" in direct experience and what is or where exactly is "other" you will fail miserably. Because this boundary is completely imaginary. It's all one thing. There is no you right here perceiving a world out there. It's all here. Here is there. You is the world.  So what you call other people are literally you. The entire actuality of what's showing up in consciousness right now is you. Not just what you are  identified with as your body. The entire field of consciousness is you. From this place there is neither  you nor a world as two separate things. There is only what is. And what is.. Is one unbroken actuality with no divisions.   you are literally the entire world. You are the totality of what is.
