Neale: Which is?
The experience of their Divinity.
Neale: So these beings cannot be killed? Not even by an outward circumstance having nothing to do with being violent with each other? Like a Black Hole ( just to make something up here ) swallowing their civilization's home?
There is no outward circumstance within the physical universe that could cause them to equate the changing of their manifested form to losing their life or ending their existence.
Neale: So moving from the physical into the non-physical isn't seen by them as the end of anything.
That's exactly right. They know that they will always exist and never cease to be, no matter what happens to their physically manifested forms.
That includes a “black hole” swallowing any planet on which they may happen to be embodying.
Neale: When you do not fear losing your life, ever, you have no reason to ever become violent? What about losing something, or not being able to get something, you desire?
You have already been told, by masters on your planet, that desire that you feel must be satiated is the cause of all suffering. And suffering is the cause of all violence. Eliminate suffering and violence goes away, evaporates, dissolves, disappears.
Neale: If you're fully awakened, if you're a Highly Evolved Being, you escape all desires?
You escape the incapacitation of desires. You escape the ruination of being ruled by your desires. When you know that your life will never end, you know that anything you wish to experience you have an eternity to create – or to recreate if you've had it once and wish to experience it again.
There's a saying in the cosmos: Eternal Life brings Eternal Peace.
If, on the other hand, you imagine that you have a limited time in which to experience what you desire to experience, you will give up your peace to acquire it, or to hold onto it if and when you do acquire it.
