ACIM is simple. You've given your power away to illusions which have no power of their own. You have projected causality outside yourself, making you an effect. You think the world is responsible for causing you, so you try to persuade it to cause you in ways you prefer. This is all backwards. Reverse this causality and you're done.
We keep making up perceptual stories about how something out there has power over us. It's causing us, affecting us, doing things against our will. And each time we believe this, we perceive this. And with each perception comes the fear of being under attack. Even believing something out there is "making you happy" must induce fear.
"I am constantly tempted to make up other laws and give them power over me. I suffer only because of my belief in them. They have no real effect on me at all."
Every single facet of victimhood is a belief that something has power over you. Every single form of suffering is a demonstration of your belief that you are being affected. Even death is an attempt to prove you are totally powerless. This is bullshit.
"I am not helpless, but all powerful."
"You made sickness and death (with your power) and therefore can abolish both (with your power)."
When you reverse cause and effect, to place the levels in their correct order, you don't merely "disempower" that which you thought was causing you. You BECOME powerful, and re-claim the position of having POWER OVER everything else. You have power over it because YOU ARE CAUSING IT. You are broadcasting the world.
"It is your thoughts alone that cause you pain. Nothing external to your mind can hurt or injure you in any way. There is no cause beyond yourself that can reach down and bring oppression. No-one but yourself affects you. There is nothing in the world which has the power to make you ill or sad, or weak or frail. But it is you who have the power to dominate all things you see by merely recognizing what you are."
To take back your power, is to become EMPOWERED. Being empowered, you now have THE POWER. Power is ability. It means you can accomplish something. You can cause something to happen. You can create or make. You cannot be victimized or attacked. Power is immortality.
Once you have your power back, do you think you'll sit on a fence and merely observe the world, as if someone else had the power to put it there? Do you think sickness and death will still have power to enact themselves against your power?
"What He enables you to do is clearly NOT of this world, for miracles violate every law of reality, as this world judges it. Every law of time and space, of magnitude and mass, of prediction and control, is transcended, for what the Holy Spirit enables you to do is clearly beyond ALL of them."
"Miracles do not obey the laws of this world. They merely follow from the laws of God."
"I am under no laws but God's."
Having power OVER the world, which YOU MADE in the first pace, which YOU GAVE laws to, means you can change and break the world's laws. It means nothing can choose for you and your will is unopposed in what it can do.
You have power over the world because its power is less than yours. In fact it has zero power. Which means when you exert your power, the world cannot resist. It doesn't have the power or strength to oppose your will. What you say goes. You make it so. You override the world and its laws. You write something new on the wall.
"The power to work Miracles BELONGS to you."
The Course is all about taking your power back and then using it to help others. Having power over the body, power over sickness, power over death, power over time and space. No longer being at the effect of anything. No longer being under limits of any kind. No longer being incapable or unable to do anything. No longer suffering against your will. No longer tolerating. No longer waiting for someone else to save you.
"You who perceive yourself as weak and frail, with futile hopes and devastated dreams, born but to die, to weep and suffer pain, hear this: All power is given you in earth and Heaven. There is nothing that you cannot do."
"There is nothing my holiness cannot do." NOTHING!!
a) cause is outside you, you are at the effect, powerless to stop it, or
b) cause is inside you, you can affect all illusions, you have power over everything AND CAN EXPRESS IT!
Choosing B is choosing the atonement. "An untrained mind can accomplish nothing".... but a trained mind, which believes in its own power, and does not see itself as powerless, can accomplish ANYTHING. Having a healed mind isn't the end of accomplishment, it's the beginning. Miracle mindedness is merely the state of true perception FROM which miracles - the POWER OF GOD - are expressed.
You are ALL POWERFUL. You have power OVER this world. It is NOTHING to you. You are in command.
