When you first perceive that someone has something wrong with them, is sick or suffering in some way, and this strikes you as real, you will have a reaction.
Your reaction will be part of what you have put in place in your mind, because both what you see in the other as sickness and your reaction to it coexist in a single split-minded dynamic.
You will react to what you've shown yourself, believing it. If it is real to you, you will be horrified and upset and will want to stop the suffering as if that will solve your upset, but the other person's suffering isn't the cause of your upset - your split minded perception is.
You will want for the person to be free of this pain or sickness or situation. You think that if you solve that, your own upset will go away, but it won't. You will then automatically start trying to fix them and change them and even force them to be different.
Your attempts to fix them will then compel you a great deal and produce a lot of what seems like a genuine desire to help, a motivation to research and figure out and find solutions. You can get into that quite deeply.
You will convince yourself that you are being caring, that you just want to help the person, are trying to heal them, want to take away their hurt and save them.
But what you don't realize is that you're doing all this as a reaction to something you perceived which frightened you and upset you. You think that your response is based in helpfulness and selflessness but it's really a selfish reaction to what you showed yourself and what you saw in the person.
Your use of them entailed you seeing truth within their sickness, believing their sickness to be real, showing yourself their illusion of sickness as though it is the truth and is really happening. That is actually an attack on your part. That is you using the opportunity to imprison them by holding these perceptions as true of them, maintaining the sickness and keeping it.
Your efforts later to get rid of the sickness, as extremely caring as they may appear to be, are actually an egoic cover-up to the fact that you are keeping the sickness in place, have attacked the person with the sickness by agreeing with it, and some part of you actually wants them to be sick.
The truth can be upsetting to admit to. Shocking isn't it, that you thought you were just trying to help and care about them and in fact you were hurting them, contributing to their suffering and keeping them imprisoned.
All you've been doing this whole time is rebounding off your own false, erroneous perception, which showed you an illusion of sickness as though it was God's given truth, which must be horrifying if sickness is the truth, and then were attempting to get rid of that as though it was in the person and not in your own mind. The making-real of what you thought was in the person, was just a projected portion of your of mind attacking itself.
If you admit to this then you will learn to stop trying to fix and heal and correct and help and solve the person's problem, because in REAL truth they do NOT have a problem. You do. YOU are upset about what you see. YOU are upset about what appears to be a real suffering. IF it were real, your upset would be justified indeed. But it's not. You are mistaken. And that means that all your attempts to help based on keeping it real and believing it's truly happening, are actually counter-attacks and are NOT forms of healing.
So all this time you thought you were trying to help, you were hurting, agreeing with what the person believes about themselves, and holding them captive to their own suffering. Your failure to UNDO their sickness is an attack. Your failure to see through and overlook the illusion of their sickness - which is not REAL sickness (it doesn't exist), is actually an attack. Since you did not forgive, you must have judged, and judgement is condemnation.
If you can admit this to yourself and collapse this whole illusory response to a misperception, you will stop trying to fix and solve the person based on what is "really happening to them." It's a false reaction, because it's not TRUE that something is really happening to them. Their sickness is an illusion, not a reality. Their immortal self is NOT threatened. There is no real danger. Life isn't under attack. Only by perceiving and believing as such do you support life and set your brother free from their imprisonment.
Once you admit you were only reacting to your own upset, because of what seemed like a really deep "genuine" feeling of caring and wanting to help and make everything better, you will see that this desire to help is really an illusion. It's part of the ego. As supportive as it SEEMS, it is not helping at all. It is just your own emotional upset flaring up into a nightmare and causing you to go on the offensive trying to solve everything that doesn't exist. Pretty funny actually.
When this denial has been undone, you are now more clearly confronted with a greater degree of truth about the situation. Your challenge now is to ACTUALLY FORGIVE what you see, to not believe in it, to truly UNDO it, by correcting your mind and offering this correction to your brother. Your lack of support for their belief that they are sick will be healing, helping to guide them towards the truth that will set them free.
Now you can be TRULY HELPFUL, by offering a miracle of forgiveness and coming from real love, which isn't a love that enters into FALSE EMPATHY. False empathy means you are believing in the suffering of others and agree with it and therefore are attacking them and yourself with it by joining in it with them. That isn't helping you or them. True empathy means representing God, genuinely, offering miracles of love, and shining a light for your brother to see.
There are parts of the Course describing miracles where it says that they shine a light to reveal all the ways that we are in error. It doesn't necessarily do anything but it reveals how we are in fear and let's us see that clearly so that we can recognize illusions and thus make them disappear. It points the way to the truth.
We must learn to OVERLOOK the appearance of sickness, instead of reacting to it. We must learn not to believe our eyes or think that this is proof. We must recognize our own ego reactions based on our own nightmare of hallucinating that sickness contains the truth. Sickness is always an illusion and if we're not recognizing that we will become upset and try to attack it with "help". That is not forgiveness and it is not healing or helpful. Such helpfulness is hurtful.
Strangely, you will become more loving and truly compassionate when you are not having your own gigantic mega reaction to someone's plight. You'll be more present and available and productive and constructive. You'll be able to truly help them and support them, rather than making it all real and going on a rollercoaster ride. It's not easy. The ego has lots of traps up its sleeves and this is one of the big ones.
