Hi Brian, now for some fun,
your right these are really intriguing questions, the one's that many people do not take the time to answer, or even realize that there is a question that could be asked.
Well, from where you describe your self at the moment is a really exciting place to be. Your answers are also very open and that's also a wonderful place to come from.
Firstly 'I' don't have the answer, because there is no "I " to give it to you. The same way as there is no "you " to hear it. These words are written and read by no one! However there is an imagined 'me' which which can talk to an imagined 'you'. No I'm not on drugs, lol. It's better than that.
The real you could be described as a 'knowing' that you exist /consciousness. You don't need any one to prove to you that you exist, you just know that from some deep awareness. As you have also noted there is no separation, that's the big illusion that sits there in this story called life. The apparent illusion that there is a me and a you, and a GOD some where else. There is only this which is God, beloved,consciousness,( oh no I've mentioned the word that should not be mentioned) or any other name you want to call it , it does not matter.
As consciousness is all there is, you could not read this if there was no consciousness, so yea, we are all one as there is no two, Two is the illusion called duality.
However as we are all one which is this thing called (it's not a thing, because that presupposes that there is an observer subject relationship) consciousness playing in the game of being two, I can write this to you and someone else can say what a load of rubbish. That's the game in action.
The game is for no one to realize that there is no one, then the game of two can be played without fear. Instead unconditional love can be lived as it should be, from the perspective that what ever you do to an apparent some one else , is actually being done to yourself, as there is only oneness appearing as two.
For those that are ready this truth will be clear, for those who are not, it makes no difference. All of this is beyond religion,creed,dogma. It is the the essance of the one true religion- the religion of Love., from which all true religions and learnings came from.
Love all - Serve all- help ever- hurt never.
That should have done your brain in !!!!!!!!!! You did ask!
