A selection of quites about the causes of physical sickness, from A Course in Miracles.
THE CAUSES OF BODILY (PHYSICAL) SICKNESS
"Sickness is anger taken out upon the body, so that it will suffer pain."
"The central lesson is always this; that what you use the body for it will become to you. 2 Use it for sin or for attack, which is the same as sin, and you will see it as sinful. 3 Because it is sinful it is weak, and being weak, it suffers and it dies."
"The body cannot create, and the belief that it CAN, a fundamental error responsible for most of the fallacies already referred to, produces all physical symptoms."
"Sickness or "not-right-mindedness" is the result of level confusion"
"Sickness is a defense against the truth."
"Its health or sickness depends ENTIRELY on how the mind perceives it, and the purpose that the mind would use it FOR."
"Sickness is idolatry, because it is the belief that POWER CAN BE TAKEN FROM YOU."
"For sickness is a meaningless attempt to give effects to causelessness, and MAKE it be a cause."
"Sickness is a demand the body be a thing that it is not."
"Sickness is but a "little" death; a form of vengeance not yet total."
"What is a sense of sickness but a sense of limitation? Of a splitting OFF and separating FROM?"
"This heals at all levels, because all sickness comes from confusing the levels."
"The arrest of the mind's extension is the cause of all illness, because ONLY EXTENSION IS THE MIND'S FUNCTION. Block this, and you have blocked health because you have BLOCKED THE MIND'S JOY."
"To believe that a Son of God can be sick is to believe that part of God can suffer."
"When a brother is sick it is because he is not asking for peace, and therefore does not know he has it."
"For sickness is an election; a decision. It is the choice of weakness, in the mistaken conviction that it is strength."
"Sickness is a method, conceived in madness, for placing God's Son on his Father's throne. God is seen as outside, fierce and powerful, eager to keep all power for Himself. Only by His death can He be conquered by His Son."
"If sickness is but a faulty problem-solving approach, it is a decision. And if it is a decision, it is the mind and not the body that makes it."
"Sickness is a retreat from others, and a shutting off of joining. It becomes a door that closes on a separate self, and keeps it isolated and alone."
"Sickness is but another name for sin."
"Perceiving the body AS A SEPARATE ENTITY cannot but foster illness, because it is not true."
"Any form of mental illness can truthfully be described as an expression of viciousness."
"We said before that illness is a form of magic."
"The mind makes this decision as it makes all decisions responsible for the condition of the body."
"A damaged body is proof the mind has not been healed."
"Damaged bodies are accusers."
"Sickness is not an accident. Like all defenses, it is an insane device for self-deception."
"You suffer pain because the body does, and in this pain are you made one with it."
"It will be healed of all the sickly wishes that it tried to authorize the body to obey."
"If you let your mind harbor attack thoughts, yield to judgment or make plans against uncertainties to come, you have again misplaced yourself, and made a bodily identity which will attack the body, for the mind is sick."
"Sickness is a decision. 2 It is not a thing that happens to you, quite unsought, which makes you weak and brings you suffering. 3 It is a choice you make, a plan you lay, when for an instant truth arises in your own deluded mind, and all your world appears to totter and prepare to fall. 4 Now are you sick, that truth may go away and threaten your establishments no more."
"How do you think that sickness can succeed in shielding you from truth? 2 Because it proves the body is not separate from you, and so you must be separate from the truth."
"Sickness where guilt is absent cannot come, for it is but another form of guilt."
"Physical illness represents a belief in magic. "
"All forms of sickness even unto death, are physical expressions of the fear of awakening. They are attempts to reinforce UNCONSCIOUSNESS out of fear of CONSCIOUSNESS. This is a pathetic way of TRYING NOT TO KNOW by rendering the faculties for knowing ineffectual."
"Pain demonstrates the body must be real. 2 It is a loud, obscuring voice whose shrieks would silence what the Holy Spirit says, and keep His words from your awareness."
"Pain is a wrong perspective. 2 When it is experienced in any form, it is a proof of self-deception."
"And idols are not wanted there, for guilt is understood as the sole cause of pain in any form."
"And you are free of dreams of pain because you let him be. 6 Unless you help him, you will suffer pain with him because that is your wish"
"No one can suffer loss unless it be his own decision. 2 No one suffers pain except his choice elects this state for him. 3 No one can grieve nor fear nor think him sick unless these are the outcomes that he wants. 4 And no one dies without his own consent"
"Let me not try to make another will, for it is senseless and will cause me pain."
"Yet can the mind deny that this is so, believing there are gaps in love where sin can enter, bringing pain instead of joy."
"How do you think that sickness can succeed in shielding you from truth?"
"When attack in ANY form enters your mind, you are EQUATING YOURSELF WITH A BODY."
"The sick are merciless to everyone, and in contagion do they seek to kill. Death seems an easy price, if they can say, "Behold me, brother, at your hand I die." For sickness is the witness to his guilt, and death would prove his errors MUST be sins."
"Atonement heals with certainty, and cures all sickness." ... "It takes away the guilt that makes the sickness possible. 6 And that is cure indeed." "Peace be to you who have been cured in God"
The message here is CLEAR. The body is NOT SUPPOSED TO BE SICK. Sickness of mind OR body is unnatural and unholy. Even death of the body is not supposed to occur. It demonstrates and proves that the person does not want to be awake and would rather be unconscious. Death is utterly unnatural and against God's will at mental and physical levels. All physical sickness is a demonstration of the presence of a false belief and an attempt to DENY HEALTH by denying God.
A Course in Miracles IS attempting to help us to see that YOU NEED NOT SUFFER IN ANY WAY, not even physically, and any presence of ANY kind of sickness CAN AND MUST be healed by miracles.
