I figure that if a being or a number of beings became aware of the fact that they are going to exist for all of eternity, they would want to find the most wonderful way to do so that is possible, and come up with something similar to what Out of Body Dude wrote.

After learning about love, not only does a being want to do so for itself, but also for every other being that exists.  Once you learn that the happiest and most meaningful thing to do is to love others, why would you want to stop?

I think the bottom line here is experience, but the whys of experience I find to be a vast and complex matter.  The more I get to know, the more also I get to know there's just so incredibly much I as an incarnation don't yet know, but then again, got to start somewhere. Some points I find interesting:

Who am I? Think this is a big one, and my experience is to peel off the layers I've learnt to go by.

I'm a <insert vehicle for the spirit>
I'm a <insert planet currently inhabitated>
I'm <insert country currently inhabitated>
I'm <insert race>
I'm <insert age>
I'm <insert gender>
I'm a <insert occupation>
I'm a <insert parent if any kids>
I'm <insert personality characteristics>

Who's behind all the layers and masks? Who's the spark that makes the body come alive?

Duality - Two opposites that create a gradation between them. No sense of height if there was only low.

Dark and light (and the merged balance)
Female and male (hard about this, softest about that, harder about other things and so on)
Cold and hot
High and low
Active and inactive
Left and right
Oppressed and oppressor
Wide and narrow
Fat and skinny
Rich and poor

Feelings - When reading an e-mail or a letter, and compare the same text/thoughts being spoken in a conversation, I like the richness that feelings can add to just about anything. Another comparison, a musical piece with rich emotional content, and a song with a minimum of emotional expression put into it.

Interaction - That's at least a big part of how I learn, not forgetting that observation of interaction can also be a source of knowledge.

Getting done with the lessons and experiences (moving on) - While many others I've met seem to live as they'd live here forever, I opt to shake off, and try to break repeating experiences which seem to pop up again and again until I've had enough of them. I really like the logo I've seen used by the monroe institute - a figure spiraling out and away from the earth. Forever. What I put into that figure is a being with newfound abilities/knowledge that makes the being ready for other adventures, which wasn't a possible option before making castles made of sand in this playground.

perhaps we are just here to love

There's different ways you can pitch this, so it's very hard to form or hold (except as an interim view) any sort of definite position as to the nature of our existence. The 'what' is tough enough to get anything beyond a tentative  grip on, the 'why' is far beyond this and probably far beyond our comprehension.

Viewed from existence in physical life it can be characterised as a learning school - one in which we learn to shed ego beliefs and resulting drives to live through love.

Viewed from Spirit we as a collective part of God mind know all of this already. Trouble is we decided to try out separation, and having done so our of misplaced fear of being punished by God for this have spent many lives suppressing this knowledge and inventing individuality in what we perceive as a reality while immersing ourselves in it - in an attempt to suppress this fear.

We're consequently trying to find our way back to where we were, to escape from the mire of misperception we have created.

Both of these though are essentially dualistic views in that both are abstract representations of our situation, both from the viewpoint of an imagined self. One conceptualises Spirit as a self, and implies the view that higher existence is good, the other suggests a core purpose for what we perceive as physical existence. That's before even we inject time as another artefact of the way we perceive, rather than any absolute reality.

Neither necessarily makes mush sense. What we perceive as worldly existence seems to be the result of our belief in it, what we may even experience as higher existence we still conceptualise in dualistic and self based terms.

Perhaps in reality these are just two relative views out of the gazillions that exist (both laterally in terms of throughout space and multiple dimensions, and along the timeline) - some of which are real or in keeping with His laws, and some artefacts of our erroneous beliefs - out of which complexity Spirit/God somehow extracts what is real, and views/creates in its entirety all at once....

Even setting aside the self interested rose tinted varieties of so called 'love' the real thing can by the way can seem quite hard or tough, or cause pain in this relative reality. What in the overall picture is best for all beings may be perceived by the self as very painful...

Group-separation-individuality

Bush, some of the alien claws http://www.youtube.com/watch?v=OzMJhOwBLqw, hitler, new age, the military, christianity http://www.youtube.com/watch?v=zImjUyC-9l8,  and the gossip club on the corner have something in common; the craving for oneness/sameness - thinking the same, doing the same, walking the same, talking the same, eating the same, blah blahing the same. And then there are some troublesome individuals who just refuse to 'be one of us'. Individuality, and diverse possibilites for experience are being eradicated. Cultures/tribes/countries have and are being watered down to a melting pot, the same icky bland denial of experiental taste. Power structures and technology are some tools for this purpose.

Should someone be forced to a one path solution because <insert autority of preference> 'knows what's best' for that someone? Why the lust for control; thought that was what the dark characters was known for? As with the being monroe met that had a peek at this playground and presented heshe as a master. Didn't work.

How can one really separate if one comes from the source? Would source experiences "itself" as smaller pieces, and become lost in the process? That sounds like a local rooted idea. I see individuality as freedom of choice not being at the expense of other pieces. But looking in the mirror, and looking around; at the expense of others happens while learning - perphaps another reason for setting up this experiental playground. Bodies may be tossed around, but the real deal isn't hurt a bit.

The now changed slogan wasn't about the war on terrorism. It was and still is the war on diversity, where might makes right. It doesn't matter if it's 'my' or 'our' tune, as long as you dance to one of the provided tunes. If you you switch over to another http://www.youtube.com/watch?v=esHEPt41Sjc, there are a growing number of mechanisms to, at least try to, reign you back in.
