There's a oneness to showing yourself to an audience. They feel that. It's healthy. That's what acting is all about.
I think the understanding of oneness and interconnectivity of the whole Universe is something we have innately, something we're born with. We are however very skillful at ignoring and pretending we don't have or know it.
The thing with the question of oneness or non-oneness is that you can literally discuss it forever. You can go into the philosophy section of any library and you'll see people have been discussing it forever and will continue to do so.
There's also an aspect which I tried to express yesterday by saying the same "something" that looks out through Curlys eyes is also the same exact thing which looks out of Moe's eyes, and that's harder for people to grasp. So the thing is, you have to find a way to ultimately embrace both sides or else you can't function. If you only embrace the side of pure oneness then you end up sort of spacing out and sitting under a blanket.
When we realise our oneness with our RULER, then the matter shall have no longer power over us, and we shall see it as the unreality it is.
