"The body needs NO healing. But the mind that thinks it IS a body is sick indeed!"
This is a difficult one to accept. To suggest the bodies needs NO healing, is not an attempt to make it "ok" that bodies are in "conditions" of sickness. It's not saying that "you should not heal the body" or attempt to be free from the physical manifestation of symptoms. Instead, it's saying that really, the body isn't the CAUSE of the problem and isn't the source of what's showing up as wrong with it.
The only real issue is the mind. The mind is the only thing that can be sick. For example Jesus says somewhere that "only perception can be sick". A sick perception projects its sick twisted mental conditions onto the body and confuses itself with the body, thus twisting the body into unnatural configurations. The body itself is nothing but a MIRROR IMAGE, reflecting the mind's condition. "The mind makes this decision as it makes ALL decisions responsible for the condition of the body."
The body makes NO decisions about its health. "The body is not sick, nor does it need healing" says the same thing. The body APPEARS sick, and seemingly "is sick", but the sickness is being PUT THERE by the mind. Since mind is the cause of the problem, fixing the EFFECT (the body) directly is only going to rearrange furniture. The mind is quite capable of re-manifesting the same or different sickness at a later time. It's like trying to fix a leaking tap by collecting the water, or trying to fix an overflowing bathtub by fetching a mop. Until the source 'tap' is switched off the problem will regenerate.
It's difficult to accept this is true because the BODY in its physical appearance is quite a convincing illusion. If you can SEE, feel, touch, forms of sickness or damage.. if you can see the wounds, if you can see the cancerous lumps, if you can have sensations of the disease etc... these are quite convincing temptations to believe "the body ITSELF has a problem". And because the body was made to blind you ("nothing so blinding as perception of form"), you think the body is the start and end of the problem. You don't SEE the projector - the mind - forcing the body into sickness, mangling its form, or attacking it. The attack is invisible.
The truth is though that the body is merely the end result or effect of the mind's activities. "All sickness is mental illness." ie, NO sickness is really something inherently wrong with the body itself. The body isn't containing "an issue". The body, even if it appears sick, isn't really "having" a sickness. It's merely REPRESENTING, or symbolizing, something that's going on in the mind. It's ONCE REMOVED from the problem. Even if you can see someone's broken leg, it is not really their leg that's broken, it's their mind. The body state is a reflection of the mental state. "A broken body is PROOF the ***MIND*** has not been healed."
It is very tempting upon witnessing the end result "form" of the body "looking sick" to want to then react to that perception. Having thus made the body real, believing the body is "really sick", falling for the appearance, buying into the story of how it came about, etc... it is then becoming a block to awareness. It now disguises the mind and hides the mind from view. It forms a wall of form, a form of error, which YOUR body's eyes are now failing to overlook. And so now you've fallen for believing in (and reinforcing) the body's condition without really noticing that its the MIND that has a problem. The mind is making the body suffer.
Essentially, the body has no mind, no will, no causality, no soul, no power, no decision, nothing. The body is totally nothing. And so the mind, in its attack upon or use of the body, is doing stuff TO the body "against its will", so to speak. The body simply responds with a reflection of what the mind wants it to represent. "Sickness is an attempt to prove you (mind) can be hurt." So the body just goes along with the mind's attack upon it and "faithfully" symbolizes what the mind wants to demonstrate, even if that is a will to demonstrate disease and death. The body has no say in it, and no will to stop it or resist it. The body has no fight, no cause, no defense.
Jesus describes the body's ONLY real defense as a state where the mind ceases to attack the body. "The mind, being sane, heals the body." So when the mind is not projecting attack onto it, to hurt it, the body is instead healed by the mind's use of it for extending Christ's love. The body is like the image on a movie screen. To fix the sick body you can't attack the movie screen. You've gotta to heal the movie projector. The projector is the mind. The mind is the only problem that needs fixing.
The question then becomes, how do you heal the mind? It seems easier to do this for yourself than for another mind. "The light in your mind can shine into another mind and enlighten it." Both minds are lit by the same lamp. Your minds can be one. This is a clue. How do you heal the invisible? How do you bring about mind correction, that's permanent, in another mind, through the broadcasting and expression of love? Through weakening their belief in sickness by not believing in their body's condition? Through prayer and the power of God moving to perform a miracle?
The focus needs to somehow move away from "I believe there is a real physical sickness" to "I recognize this physical sickness is not real whatsoever and the mind needs healing." And then proceeding to take steps to heal the mind directly. The body will follow.
