"I came to tell them that death is an illusion, and the mind that made the body can make another since form itself is an illusion."
Let's say the body is nothing more than an 3D IMAGE which the mind is projecting outward to make "visible." Like a movie projector. The image is shining outward and only shows up while the mind is projecting it.
Is the image alive?
Would you feed an image? Does it need water?
Would you try to protect an image from the weather?
Would an image be able to age or grow old or die?
Would you be able to attack an image?
Could an image become corrupted or broken or damaged?
Would an image be subject to laws of physics like gravity?
Is there any causal power in all the universe that could do anything to change that image?
If it's just an image, and if the mind is making it appear, and nothing you can do can affect the MIND ie you can't stop the movie projector from projecting, then surely the image of the body is absolutely unchangeable if the mind decides that this be so? And no matter what seems to happen, nothing affects the image because it only comes from the mind? Even if there's a nuclear explosion nearby, the next "frame" of the movie is simply projected in the next instant making the body seem totally unaffected?
The body is just an illusion. It is an image being projected by the mind. It has no real purpose, substance, reality, live, will, mind, causality, nothing. It's just an image. A hologram.
The last time you watched a movie, for the second time, did you get a different movie? Did the movie "age" and become sick? Did the movie need feeding? Or did you see the exact same movie? Because the SOURCE of the movie did not change the OUTPUT, right?
If you do not attack the image with your mind, and you do not make the image BE an image of sickness or death, is it possible for the image to be anything other than what you choose to project?
When you believe or think that the image you are projecting IS WHO YOU ARE, that it is your identity, that is when you have moved into the ego and are now confused and lost. It is in this identification with the image that you lose sight of your true self, become deluded and self-deceiving, and don't realize that nothing can affect YOU who are not a body, and start to fear that the body AS YOU is vulnerable. Yet the only thing that CHANGES the body is your mind - this is the secret of salvation - you do it all to yourself.
What you use the body for it becomes. Let's frame it differently. What intent you have behind projecting a body, determines what kind of body you project. If you want to attack, you create an image of an body with "attack in it", and this attack shows up as a different appearance than if you made a body just to communicate love.
When the body is ONLY showing a representation of Christ/love, it does not show up with any self-made attack or intentions or harm. Then the body seems "lovely", as Jesus refers to it. At least while it is useful to keep showing one. And when you are doing pretending to be a body, you will just stop projecting it, and it will disappear.
When the mind has become fully spirit identified and free from believing it is a body, it is now free from the delusion of form or separation, and yet CAN STILL project a body if it wants to. This is what Jesus demonstrated when he reappeared a body. "The mind that made the body can make another." Yet in the making of it, he is not deceived by it. This is also why you can still call upon the "image" of those who have gone beyond the body. The body simply becomes "optional", and unnecessary, except for teaching purposes.
