Light is truth. You can see what really is, when there is light. You cannot see in the dark. Darkness appears to hide the light, as though blocking it, removing it, or affecting it. But light cannot be affected by darkness. Darkness is always affected by light, because light dispels it. Even in the dream world, light dispels the darkness.
In awareness, in your mind, the light of truth reveals to you what the truth is. In awareness of the truth, everything is revealed. Whatever the illusions were, they are seen clearly and understood to be only what they are and nothing that they appeared to be. They are nothing.
The light itself is enough to clarify the matter of whether the ego exists or not. The light shows you that there is no real ego. The light clearly reveals to your awareness, that all of the things which you thought really happened because of separation, actually have not happened.
The light also shows you something very important. And it's simply that, in the light of truth, nothing has really gone wrong, so there is nothing that you need to do "extra" to deal with the wrong stuff. You don't need defenses against it, you don't need special skills to deal with it, you don't need a special technique or a meditation or a set or rules. Your behavior doesn't matter, you don't have to effort to interpret things differently.
There simply has not been anything that has gone wrong. There is no ego, no world, no death. They were just illusions and tricks all along, pretending to be real but being nothing but fantasy. This is all *recognized* in the light. The light shows you that this is true. So it's not like, you suddenly realize that there's all this shit going on and now you have to deal with it. Its a recognition that there is not really any shit at all! None. Zero.
And then instead of having to constantly be at war, to defend yourself against the ego, you instead have cause for celebration, because you suddenly see that every single form of suffering was pretend, make-believe, illusory and fake. There was not a real separation. There was not sickness or suffering or death. It was all made up. And all you needed to do was to RECOGNIZE it for what it is - literally nothing.
The light is not concerned about the ego. The light is not upset about separation. The light does not fear the consequences that separation seems to cause. The light is just full of joy and celebration, in the recognition and knowledge, that God's Kingdom is completely intact, safe, unharmed, filled with eternal life, and absolutely nothing has ever gone wrong.
The light shows you this. It's a perspective. It's a correct way of looking. Its True Perception. Vision. The ability to see "what is" and, in that light alone, see that everything of the ego is simply false, untrue and not real at all.
Isn't it great news to know that absolutely nothing has ever really gone wrong, and all the stuff that seemed to have gone wrong was just a bad dream? That in reality, there is only the light and the joy and the peace? And that's all that there is? :-)
Its the big secret that all illusions attempt to hide. That there really has not been a separation at all, God is unchanged, You are still your True Self, you are still absolutely worthy of and welcome by God's love, and there is absolutely no reason whatsoever to be upset or afraid? This is the truth. This is the atonement of God. Reality is a HAPPY reality. All else is just a nightmarish illusion that isn't even real at all.
There is no true or valid reason to be upset or unhappy, ever. There is only justification for eternal life in joy and peace.
