"I am still as God created me."
"You are immortal and you cannot die."
One of the major hurdles in the separation, is that it has actually made yourself distant to yourself. There are blockages, barriers, obstacles, obstructions, walls, that have entered as the "split" in the mind, seeming to come in between "you" and your real self. And now you seem to be split off and apart and you do not know who you are anymore. And who you think you are is not who you are.
Since your real self is invisible to you, and the body cannot see it, and it's hidden behind the belief that illusions are real, and this in turn projects as a seemingly solid world that hangs as a veil in between you and everyone, including your real self and God, it really makes it hard to be in touch with the big-picture you.
For example, we should focus on what your real self is like. We should identify your immortal nature, the fact you ARE NOT sick, the fact you ARE NOT insane, the fact you CANNOT die, the fact YOU ARE NOT UNHAPPY, and the fact that you are completely perfect and whole. That is actually true of your real self right now, and always has been, but it is hidden from your awareness.
The mind, in its split state, is in a state of disassociation. And the part that seems like your current conscious self is kind of in the dark about who you even really are. This poses a problem because it now implies that you are not responsible for the state you are in. And it becomes much harder to compare the state you're in to the state you REALLY are in.
If you could SEE your immortal self, things would be so much easier. You would see obviously and easily, that your real self is totally unharmed, perfect, invulnerable, has absolutely no signs of sickness or death, is totally joyful and happy all the time, cannot be attacked, and is still the same as God created it. If you could even just GLIMPSE that for a second it would be enlightening.
If you COULD see that, or even conceive of it, it then would help you to put everything in perspective. You'd recognize that given your real self is TOTALLY HEALTHY, you would instantly recognize that any belief you have in sickness, any suggestion that you are sick, any notion of sickness existing, any damage that seems to be showing up, any mental illness, would all be immediately INVALIDATED. It would be shown to be patently FALSE AND UNTRUE. Because here is your real self, shining and bright and clean and new, and completely perfect. And all support for sickness would be removed, causing it to vanish instantly.
This also brings with it extreme responsibility. Because it now becomes clear that, given your real self is immortal, ANY suggestion on your part that you are mortal, vulnerable, hurt, damaged, sick, unhappy, upset, attacked, threatened, in fear, guilty, sinful, suffering in any way, MUST all be a total lie. It MUST be a way that you are faking it and lying about who and what you are. Just even one little glimpse of the truth about yourself would show you that. And then you would never be able to see these thing in the same way again.
In light of the fact that your holy self IS PERFECT NOW, and in light of the fact that your holy self IS YOU, and your mind is its mind, it really is "something you are doing to yourself" when it comes to any form of suffering. This is why the secret of salvation says you are doing this all to yourself. You are making your sickness, you are making your unhappiness, you are claiming your own suffering, you are punishing yourself, you are self destructive, you are the one trying to make yourself die, and you have given yourself sickness. And all of it is an attempt to PROVE that you ARE NOT who you really are.
The aim of these things, of course, is to KEEP you in the dark and keep your real self HIDDEN. So that you are not aware of the FACT, that what YOU ACTUALLY ARE, IS an immortal spirit being. The FACT that THERE IS NO SUFFERING in you, YOU ARE NOT SICK, and you can NEVER die. The PURPOSE of all the efforts to believe otherwise, is to BLOCK awareness of the FACT that there is nothing wrong with you. To disown your immortality and hide from it, to pretend it's not true of you. That is nothing less than dishonest and unauthentic. It is denial.
How you think of other people works along similar lines. Since you can't seem to see them (unless you have strongly developed christ vision), it makes it hard for you to SEE their real self, the SEE their holiness, their harmlessness, their immortality. Yet it is by acknowledging, recognizing, seeing their immortal self that you become able to heal them. You can see this FOR them, even if they in their own mind are in denial of who and what they are. Even if they are convinced they are sick and suffering, YOU can deny this and know the truth that they cannot be this.
In one way or another, either through direct experience or through concepts, it's very helpful to keep the perspective that your immortal self, and the immortal selves of others, is the ONLY truth about us. And any efforts to suggest otherwise cannot be true. And the closer you can get to experiencing and expressing FROM that truth, the more you can be helpful to those who do not know themselves. You can remember them FOR them, and thus help them to remember they are immortal.
