"your ISBE is a bundle of energy with your unique frequencies. So you could say it looks like an orb."
The ISBE is a singularity. Most people don't know what this even means, because they can't comprehend what a singularity looks like. I'll try to explain:
There are two essential realms in reality: the mental realm (there's only one) and the physical realms (there are many, we call them universes).
Now think of an ISBE as a lense that projects individualized thought from the mental realm into physicality. That lense is a singularity, like a mini black hole, if you will. Now it gets weird: That singularity is not limited to one point, but makes the core of every atom of your body. Because physical matter is a holographic projection, and like in every hologram, the center is everywhere.
Think of it as one point dividing itself into billions of connected points distributed within spacetime to form a body. The ISBE essentially does the same thing that God did when the universe was created. As above, so below.
And that projected form makes waves within spacetime, which is your frequency.
What you call the physical body is just one layer on top of it, so to speak. Your projected form is attached to physical matter, informing it and getting new information in return. This means your projected form assumes shape of the body as it is growing (because the information goes both ways).
When the physical body dies, your projected form remains in the shape of the body, because that's how you have been informed. If you don't know that it works that way, you will confuse your projected form with a physical body. And that's not even wrong, because all form is physical. We use the term physical to describe what can be touched. Your projected form can touch other projected forms that are in the same state, because the different frequencies will interact with each other.
So, the term "physicality" actually is misused here on Earth. Whenever you can touch something, it's physical. Your projected form – let's call it ethereal body – can touch other ethereals.
And you don't have to be an orb. You can reduce yourself literally to a point in spacetime to make yourself untouchable. Many ISBEs seem to have lost that ability because they identify with a form, and losing that form is perceived as death. But you won't die, because your identity is within the mental realm – or with God, if you don't have a problem calling it that.
