"The higher mind thinks according to the laws spirit obeys, and therefore honors only the laws of God."
Since spirit obeys only God's laws, and Spirit is love, expressions of love (miracles) are expressions of the laws of spirit. Spirit is beyond the "nature" of the ego, and therefore miracles have a super-natural, spiritual origin. What you may not realize is that this entire world is constructed from the ego's fake laws of nature, even down to the subatomic physics.
The laws of the ego are invented by the ego. The dream, which is an effect of an "invisible" higher-level cause, does not contain any real causes. But it contains illusions of causes. These illusions of causes make it seem like one part of the same level causes effects in other parts of the same level. This is not true. All effects are orchestrated from a higher level, including the illusion that one thing causes another.
So when you study this fictional "world", and you see one object seeming to move and collide with another object to "cause" it to behave differently, this SEEMS like there is some kind of a law involved. Like the laws of physics, suggesting that actions have equal and opposite reactions.
The truth is that actions do NOT have equal and opposite reactions. Actions on this level are not actions. They are all reactions - effects, pretending to be actions. The action, and its effects, are both effects coming from an unseen dimension.
The ego has been very clever to disguise and hide God's nature and the laws of Spirit, by creating FORM, and nothing is so blinding as sight of form. The behavior and interaction of forms creates an illusion of cause and effect happening on this same level. And so on this level it appears that some things cause other things, and that this is "natural". It could not be further from natural.
What it really expresses is the fact that what is not love is murder, and every part of the ego thought system (of which this world is a part) is murderous. The ego thought system believes that what applies to one thing does not apply to another, therefore there are differences, therefore you can cause (attack) without being attacked (affected).
This is why so-called "causes" in this world seem to escape the effects they inflict on other things. It seems possible to throw a brick through a window without damaging the brick. But since what applies to the brick does not apply to the window, this is an illusion based on differences, and is an expression of a murderous idea. The brick "gets away with" (murders) the window because the so-called properties of the brick (the laws applying to it) are "different" to the properties and laws of the window. It is not "natural" to be murderous, and so this "law of nature" that the brick will break the window is NOT being governed by a natural law or the "laws of physics".
The truth about this universe/world/planet is that it is not run by laws of physics, there is no such thing as physics, and in fact it is run by the mind from a higher level. And it doesn't really exist because it is just a dream being projected and dreams are fictional. This is why "there is no world."
Since all true causality is in the mind, and all of the mind is "above" the level of this world and its effects, when the mind decides to exercise its ability to cause, it can "modify" the content of the dream, or rearrange it, in order to demonstrate and prove that it is NOT really governed by the ILLUSORY LAWS, but by the laws of spirit.
Since spirit is love and love's expressions are miracles, these "acts of love" demonstrating the true laws or "true nature" of existence, MUST DEFY AND BREAK the illusions of horizontal laws that the ego assumes are true.
If a child is playing with a train set and the train is traveling around the track "on rails", seemingly by itself, following physical laws, it can only go where the "laws" seem to tell it to go. However, if the child reaches down and picks up the train and positions it in a totally different section of track, all of those laws are completely defied. Indeed, another child may complain that "you're not supposed to do that" because it breaks the ILLUSION of the game they were playing at PRETENDING the train is going around the track on its own.
The mind of the dreamer is what dictates what shows up, where it shows up, how it shows up, and how it behaves. Any so-called "interactions" of objects are FAKE. The objects would completely pass through each other and occupy the same space if it were not for the MIND deciding to make it seem like they collide with each other and perform a cascade of so-called "reactions". There is no such thing as a real reaction. Spirit creates and extends, it does not react.
This whole world and everything in it was designed to conceal the nature of God and His laws, behind a smokescreen of fake laws and fake nature. To present an illusion that one thing depends on another or causes effects in another, thereby expressing the ego's insane idea of un-equal laws or finite laws which apply only some of the time to some objects. After all, not all objects are causing something to happen at all times, and even objects which are affected turn around and become causes soon after. Are they causes, or effects, or both, or neither?
Nothing in this world has the power to express the laws of Spirit on its own because "form" is the form of ERROR, and error is all about separation and powerlessness and fake causality. Miracles HAVE to express something which is BEYOND the nature of this world, in order for them to be miracles at all. It is not a miracle for a car to drive down a road. It is a miracle for the car to disappear and reappear 50 miles further along in a split second. It is not a miracle for a tree to catch on fire. It is a miracle for the tree to avoid being burned in the midst of a raging forest fire where everything around it was incinerated. Ego laws MUST be defied in order for it to be miraculous.
Miracles obey the laws of Spirit, not the laws of the ego. For a miracle to express, something which the ego APPEARED to establish as true is shown to be FALSE, and is demonstrated to be false, by completely defying and breaking and overriding the ego laws to produce effects which are outside those laws. This would include for example giving someone new eyeballs after they were born without any eyes. Or re-growing a missing limb. Or turning water into wine. Or walking on the top of the ocean without sinking.
If this nature-defying, thus super-natural element is missing from miracles, and if miracles in ACIM are not super-natural, then what are they? There is nothing super natural or ego defying or ego-law-breaking about shifting perception. There is nothing ego-law-breaking or capable of demonstrating that the laws don't apply, in correcting some thoughts. There is nothing that's going to change the direction the world spins when some old emotions are released. There's nothing particularly powerful about any of these efforts at purification. They are just clearing away belief in ego laws to make way for Spirit to express itself.
