Every person chooses two primary paths creator or consumer: either to add to the fabric of creation or to consume creation for temporary peasure. We are created to be creators. Our imaginations make us human. This is why pride is such a tremendous sin. It is a creation of the self adding nothing to the universe. Pride is also so very close to enlightenment. I find that when I am closest to a truth I share it with a mind to boost my own ego. There is certainly a daner here, but this need not mean truth when found should not be shared.
As humans we create other universes when we tell good stories. We add to the metanaritive. Our creations in this world do not remain. Even the great ones will eventually fade. I know now that it is our creations in the next world that will remain. This fallen existence is practice. Here we are alowed to create to are hearts desire and not worry about the perminency of our creations, but a fallen creator will create his own hell. Even so, our God has given us creativity and imagination for a reason. You do not have to be a God to create. Jesus did not come to save us and make us all the same. Like him yes, but there is enough room in his likeness to stretch out and make yourself at home.
Modern media has lost something. We try so hard to make our stories believible that they loose their creativity. We try so hard to make our stories unique, to make a name for ourselves that we never fill in the gaps and our universes fall as iconic avatars to nothing. The metanarative is not merely a doctrine. It's core is concrete, never changing that is true, but the surface of the metanarative is ever changing. Whenever we dream up a new possible world, or even an impossible one we add to the substance of he creation. The metanarative is a anchor, a firm foundation on which to build our proverbial houses.
I incourage you the reader to write your own world. Make your appendix to the novel of reality and tell it from within your being. You have been made with a unique story to tell. Even if you never enter the world of esteamed writers or litteraty geniouses, you will discover your place in this world and the next.
