If you believe you are part of a dream, made of dream stuff, you can be attacked. If you recognize yourself as the dreamer of the dream, outside the dream like the container in which the dream is taking place - the mind - then you cannot be attacked.
"If you let your mind harbor attack thoughts, yield to judgement or make plans against uncertainties to come, you have again misplaced yourself, and made a bodily identity which will attack the body, for the mind is sick."
The dream of death, space and time, the world of sin, is all taking place in thought. If you identify WITH this thought, you shift your sense of "who and what I am" away from "that which thinks" to "the thought itself". Away from mind to the dream.
To do this requires that you deny what you are. To deny your soul. Doing this invents perception, and doing it a lot pushes you towards false perception. Here, you believe that since you are a dream, or part of a dream, or made of dream-stuff, the dream ITSELF must be your creator.
This now begins the process of believing that you are at the effect of the world. If you are identified with or as something IN the dream, then you are now vulnerable to anything that seems to take place in the dream. And anything that happens to dream stuff, you will believe is happening to you.
"You are immortal and you cannot die. But you can confuse yourself with things that do."
By confusing your SELF, with dream figures, ie by believing you are a body, and by extension actually believing that you ARE THIS WORLD ("The world is perception"), you position yourself at the EFFECT of the dream, and introduce all manner of suffering into your experience.
If your identity is something OUTSIDE OF space and time, something BEYOND the body, something more encompassing than the dream world itself... if you are the MIND that is dreaming it, or even better, the soul that is using the mind to dream it, then you are FAR BEYOND the reaches of the dream itself.
"You are safe in God, dreaming of exile"
"The Kingdom of God is perfectly protected. Nothing can prevail against it."
"Nothing can prevail against a son of God who commends his spirit into the hands of God."
"For you would not react at all to figures in a dream you knew that YOU were dreaming. Let them be as hateful and as vicious as they may, they COULD have no effect on you, unless you failed to recognize it is YOUR dream."
Believing that you ARE a part of the dream, lands you directly onto the battlefield. The dream is the battlefield. If you are a body, and "the body is a dream", then you will believe that you are fundamentally unsafe, because the body is exposed and susceptible and attackable and limited, in the midst of a harsh and hostile world full of danger.
"Today's idea will eventually overcome completely the sense of loneliness and abandonment which all the separated ones experience. Depression is an inevitable consequence of separation. So are anxiety, worry, a deep sense of helplessness, misery, suffering and intense fear of loss. The separated ones have invented many "cures" for what they believe to be "the ills of the world." But the one thing they do not do is to question the reality of the problem. Yet its effects cannot be cured because it is not real."
Anyone believing they are a body cannot truly feel safe. They must live in fear. To believe you ARE a body requires that you believe you ARE the dream. And to believe you ARE the dream requires you to believe you are at the EFFECT of the dream or dreamer. That you are defined by it. And that means the dream is the cause of you. And being able to cause you with an alien will is an instant threat to your peace.
It can never be, that you can say, "Look at me, I'm a man, I am fearless". And it can never be, that you can say, "Look at me, I am a fierce and powerful woman". By identifying AS a body or a gender identity, or the attributes of the flesh, or the size and shape of its form, or its abilities, you are literally positioning yourself as a target for attack. And this belief in attack is inherent to seeing yourself AS a portion of a dream, and it is your own mind that is doing the attacking because it believes in being affected.
You cannot be "an invulnerable man" or "a bullet-proof woman". But you can be an immortal spirit, a soul, a child of God, who temporarily utilizes the dream body for a higher purpose, and therefore infuses it with life and protection. But this is a miraculous supernatural act, in which a power NOT OF THIS WORLD, from outside the dream (holy spirit), is used to OVERRIDE the physical laws of the dream.
It all hinges around the simple question of identity. Who or what are you? What are you identified WITH and AS? What is your NATURE? Are you made of illusions? Are you a reality? Are you something in space and time? Are you eternal and timeless? And this really boils down to the question or, where did you GET your identity from? Where did your TRUEST NATURE come from?
The answer to that comes down to, who is your father? Or who created you? What is your source? How did you come to exist? Because in that question lies all the facts about THEIR nature, and WHAT they could do in your creation, and WHAT you INHERITED from them. And if the ego is your daddy, then you are a mortal temporary limited fictional character in a spacetime of hell. But if God is your daddy, then you are immortal and permanent and can never be affected by dreams.
"The ego IS therefore a confusion in identification, which never had a consistent model, and never developed consistently. It is the distorted product of the misapplication of the laws of God by distorted minds, which are misusing their own power."
"We said before that YOU are the will of God. His will is not an idle wish, and your identification with His Will is not optional because it is what you are."
"All these things are cherished to ensure a body identification. They are songs of praise to the ego. Do not put your faith in the worthless. It will not sustain you."
"In his complete identification with the Christ, the perfect Son of God, His one creation and His happiness, forever like Himself and One with Him, Jesus became what all of you must be."
"Now are we one in shared Identity, with God our Father as our only Source, and everything created part of us."
"The Son of God is my identity."
"Then I lose myself in my Identity, and recognize that Christ is but my Self."
"The step I take today, my Father, is my sure release from idle dreams of sin. Your altar stands serene and undefiled. It is the holy altar to my Self, and there I find my true Identity."
"You I choose, and my Identity along with You. Your Son would be Himself, and know You as his Father and Creator and his Love."
"Long ago we said this course will teach you what you are, restoring to you your identity. And we have already learned that this identity is shared."
"The idea for today presents a very different view of yourself. By establishing your Source it establishes your Identity, and it describes you as you must really be in truth."
"His brothers share his name, and thus are they united in a bond to which they turn for their identity."
"They do not realize that, to deny God, is to deny their own identity, and in this sense, the wages of sin IS death."
"Choose once again what you would have him be, remembering that every choice you make establishes your own identity as you will see it, and believe it IS."
"But there is need for help beyond yourself as you are circumscribed by false beliefs of your Identity, which God alone established in reality."
"I am not an illusion but a reality."
