Not being fully aware of everything will lead to false conclusions. This is the state of insanity. Meanings will be read into, there will be hallucinations, there will be a twisting or purposes, relationships will be interrupted, and reality will become corrupted, making it seem as though everything is out to get you and you're experiencing a nightmare. Justifications will arise on a false basis and there will be many mistaken perceptions.
Unconsciousness, i.e. unawareness of the whole truth, HAS to lead to you trying to make sense out of what you are experiencing, and HAS to lead to you making a false conclusion about that experience. Until you are fully aware/enlightened, you will be making perceptual errors, deciding things which are false, and will believe that someone else is causing something against your will.
Anger seems perfectly rational and sensible IF, given a blockage to awareness, there is not enough awareness of what you are doing to yourself, what you have asked for, or how you have attacked yourself. This WILL give rise to the seemingly sensible/logical conclusion that you are justified in being angry, because someone else SEEMS to have been the cause of your problem. Blocks to awareness are the sole cause of this mistaken perception.
If you could see the whole picture and have access to all of the information, everything would be in its proper perspective and seen clearly for what it is. This would lead to no distortions or confusions. Perception would then be "true" and it would be impossible to believe, or perceive, that anything can ever happen to you against your will.
If someone else SEEMS "clearly wrong", or its their fault, or you're a victim in some way, you MUST be partly unconscious and partly insane. This is why anger is never justified. It can only seem justified when, based on all the available evidence, it seems as though someone did something that you did not do. This is a false conclusion. Some facts are hidden from awareness behind walls of denial.
Our mind, even IF we think we are fully aware, fully ourselves, in our right mind, being sensible and logical, still has some pretty major blocks of denial. There is stuff which is unconscious that we do not even realize is there. Our denial has shut it out of awareness. We have no reason to suspect it is even there, and we don't want to. The purpose of the block to awareness was to implement denial, so that we would not be aware of the whole truth. This has left us with a sense of "fake innocence" which is unaware of the ways in which it is attacking and denying the Self and the Self of others.
If we seem innocent, or a victim, or justified in anger, or it's someone else's fault, or we're upset in any way, we MUST not have seen the whole truth. Even if we search our entire mind for any possible trace of evidence that WE are the one who made ourselves upset, sick, diseased or dead, we still will not find the evidence because it's been made unconscious. There are facts OUTSIDE YOUR AWARENESS, repressed by your ego's persona/mask, and hidden behind your belief that you are completely innocent and "whole" already.
Your wholeness of yourself, the extent of the awareness of your "self" right now, the limits that define the ends of you and the beginning of otherness, IS NOT the whole of who you are! Perceiving yourself as whole when you are in fact only partially conscious is an error that will lead to confusion and the "sensible answer" of finding others guilty for what you do not SEE that you did to yourself.
This fake mask or persona is a facade of denial which is covering up your mind, and was the entire reason you entered a body to begin with. The body, not created by love, and not innocent, yet pictured "as if" innocent, is a deliberate attempt to cover up the truth using denial. The body is a denial of Self, it is a denial of Life, and it is a denial of God. It must be undone and removed from awareness in order to remove all blocks in awareness and reveal the WHOLE TRUTH.
The truth of who you really are, is so whole and so full and expansive that it is literally unlimited and far-reaching and limitless. You are bigger than the universe. But you are pretending to be little so that you can escape through denial and keep your little private world of death.
