The way Jesus describes the separation from God, there's a huge laundry list of aspects to this "state" that we've entered. The whole entire ego thought system and all its contents, has been given many labels by Jesus. Labels which simultaneously apply to all of it.
He describes the separation as a "detour into fear" for example. He describes that any state where there's even a slight lack of love, as a state of sin. He describes the whole of spacetime as the idea of death, in that "without the idea of death there is no world" - an entire dream of death. He describes that any state less than wholeness will induce sickness and disease.
He also equates sickness with the denial of God. He equates sin with insanity. All forms of unforgiveness ie judgement come into it. All physical sensory states of false perception. Every conceivable form of attack and murder, war and destruction. ALL of it applies to the WHOLE system. Even though it may appear that all these things are *separate things* unrelated to each other.
That means that everything in the ego thought system is a state of fear, death, sickness, judgement, false perception, confusion, insanity, sin, murder, evil, unreality, war, conflict, suffering, denial etc.
What this then tells you about the true nature of fear, is that when you are afraid, you're not just having a small emotion of fear. You're actually "doing the whole system".
You're being entirely ego. And it's a total package deal, in which you are doing all the other aspects of the separation as well. Fear is an attack, fear is denial, fear is conflict, fear is insanity, fear is sin, fear is death, fear is sickness, fear is deception, etc.
If you also consider the split mind, given that Jesus also refers to the separation as a matter of dissociation, going into a dissociated state means one part of your mind is seemingly cut off from the other. This happens in fear. In fear you believe that you are a victim and not a victimizer, that something is happening to you against your will, and you're not the cause of it. It's a state of projection and blame. Fingers are pointed anywhere other than yourself, so that you're totally out of touch with the fact you're threatening yourself.
All special relationships are affected by fear as well. There is mistrust, inequality, and idol worship, all of which inspire a sense of fear that the other person will take away what you lack. Or even the fear that you've given them the right to do something to you. To be special is to be at war, which means to be conflicted, therefore uncertain, therefore afraid. The entire fall of man is a fall into fear - a detour into fear.
(re leaving the garden of eden, being cast out of heaven) "There is, however, considerable clarification of this concept, which must be understood before the real meaning of the "detour into fear" can be fully comprehended. "
We need to understand how and why fear is not just fear on its own, separate from guilt, or separate from death, or separate from sin. We need to RECOGNIZE that ALL the attributes of the ego ALL go together. You can't be participating in one without the other. Fear is actually death. Fear is actually sin. Fear is actually every possible aspect of the ego system rolled into one. Just as death is sin and war is murder and blame is guilt and insanity is judgement.
When you are afraid, you are not "just afraid", helpless and weak and unvinvolved, or cut off from the other ego aspects. You must also be being unloving, attacking, murderous, blameful, judgemental, hurtful, guilty, deceptive, confused, insane, sinful, etc.
Eventually we have to realize that all aspects of the ego system are ONE system, one idea, one problem, one state, calling for one solution. To not be deceived by the idea that you can be participating in only a little part of the system and not the whole thing. All illusions of the separations between these different things are not true. The entire ego, the whole separation idea, is rolled into every part of it. It is all the same.
