You can do it by attempting to demonstrate that you can be attacked. You do this by trying to attack yourself or your body, bringing about states of "sickness" which symbolize separation or which try to show that you are not immortal in some way.
You also do it be projecting ownership of everything onto someone not yourself, giving away all of your power, being irresponsible, being two-faced, lying, hating, attacking others to prove that attack has real effects, or by trying to make out that you are someone other than yourself.
You also do it by inventing an illusion of death, which tries to demonstrate that what you are can be destroyed. It cannot, but you try anyway. And when you try, even if you seem to destroy the body, it still does not destroy who you are because you cannot stop being immortal spirit.
Nothing you can do can change what God has created to last forever. He sustains your immortal spirit in an eternal, timeless act of extension. Everything that you are, is an expression of what He is - everlasting love. Your Life is your immortality. Life sustains you indefinitely and without limit. You are in a constant state of perfect health and cannot be harmed or changed or influenced in any way whatsoever.
But you still try to. This entire world and all of the bodies in it and all of the events and sicknesses, disease, war, suffering, conflict, it is all an attempt to prove that it is possible to be other than God created you. It's an attempt to prove you can die, you can suffer, you can be upset, you can be limited, you can fail to perform miracles, you can be at the effect of the will of another, you can be victimized, you can fail to have any ability whatsoever to influence the environment, and that you have no power over anything.
You've done a great job of being upset, and believing that you are upset for a good reason, that it is justified, and that you should be unhappy. The reason you are unhappy is unjustified. You've also done a great job of creating reasons and justifications for why you are unhappy, none of which are valid. You've also created a long list of grievances which all seem unresolved, because you think that they actually are important, not to mention all the important things that you think you have to do today, none of which matter.
You are immortal spirit. You are already complete. You are already as God created you. There is nothing you can add to what God created. There is nothing that has been taken away. You've already received what God has given, and it has been full and abundant and total. You are lacking nothing. There is no lack of love in you. God has not changed his mind about you. And you are still as God created you. You're done! So what the fuck is all this other bullshit? lol
