"Direction. We live on this planet with a working concept of it ... North, South, East and West. We all know what they mean and use them to reference our movement. Two of these are destinations. Two of these are directions. What does that mean? Well, if you set out on a path North and don't stop, you will eventually find yourself going South. Likewise, if you move in the direction of South, at some point you'll pass South and be traveling North. North and South are fixed points. East and West are not that, they are directions. Travel East and you will always be traveling East (though you will eventually repeat yourself). Likewise, move West and you will always be moving West. We live with and are accustomed to these parameters even though we hardly think of their meaning.
But if you were to leave this planet all of it means nothing. There is no North, South, East or West. In relation to this planet there is only back to it or away from it. Direction become something else relating to the larger universe.
Most of us don't actually leave this planet or it's sphere of influence. We fly in planes. Some have left it's gravitational pull for a time and returned. A hand full have even broken ties with earth, circled or landed on the moon and returned to tell us all what it was like.
Imagine all of this as a metaphor to life, death and beyond. We live within the directional parameters of this life and can imagine but have no experience of anything else. Some say they've seen a glimpse beyond it all and we rush to wonder and speculate. If only someone were to truly die, truly understand life beyond it all and return to explain it to us. Now that would be someone to listen to."
