I like this way of looking at it.

What a wonderful metaphor! It goes along with my views almost completely.
The way I see it:
Each "avatar" is a viewpoint a person assumes, complete with role, etc. Yes, like living a life.
But your son never forgot he had a body and is a person outside the game. He just found the game more interesting and absorbing.
You assume as if you were there and know him.
Before graphical RPG's, we used text games on BBS's. I used to run a Major BBS and I was obsessed with winning.
My attention was in the game and for me to advance required timing and knowing the other players "avatars"
I could actually feel when a player was online and I would get up at 3am to enter the game. Yes, they were online and playing.
In that regard, it wasn't about forgetting my human body, I did however give it a lot of attention including my spiritual perceptions of the other players.
The difference between those games and the "game of life" is: We have lost sight of our spiritual selves. We give our attention to the bodies that to our "point of view" it has become more real that the real us.
If he found the game boring, unpleasant or stupid, he would leave it.
The suicide thread is at another place.
Like looking away from his video game to see what else is around. Like >waking up from it when his attention is elsewhere.
That's not what I did. This is before internet and I had to dial in with modems. I flew to Hawaii and had to get into the game. I dialed from Hawaii to discover an aggressor had conquered my planets while I was in flight.
I knew it! I could feel it! I dialed in long distance and discovered it was true.
fortunately, due to my demise in the game, I was able to relax and enjoy Maui.
And he would re-assume his bigger viewpoint, his full personality as you know him.
Big assumption. don't underestimate the obsessions of humans. Clearly on this board we have many demonstrations of how someone can be obsessed with being a body.
Our bigger viewpoint is always there. But we can only assume one viewpoint at a time.
A big assumption. Why do you suppose so many people in the world "FEEL" that there is more to life than what meets the eye?
If our bigger viewpoint was so clear, we would not have to "FEEL" it, we would see it and know it.
I have personally experienced having multiple viewpoints at once in life.
Are there other bigger viewpoints we have? Who knows? Does it matter?
It is good to know thyself!
Your son didn't bring a bunch of junk out of his video game back with him
Oh yes he did. He was obsessed with the game. He spent his real time
( real time= life), planning his next Avatar, buying and selling of items on ebay.
I suppose it is possible someone can go entirely on automatic, but even then - they still die. And in doing so, they wake up to the bigger viewpoint.
I am not sure if you are referring to Role games or life. Amazing how similar they are.
in the RPG, they simply make another life and continue from where they died and collect their stuff before it is lost.
In life, ...Only at Death, usually about three days afterwards, does someone finally wake up to their larger viewpoint. What a waste.
