You are always at the "apex" of your cohesion as an individualized soul, even if this apex may appear a "less than you can imagine." I want you to consider not just your entire life, but all your prior lives. If you do not believe in reincarnation (or variants), then consider all the lives of your ancestors ; consider the "code" that you believe is in the DNA that was cultivated by the lives of your ancestors -- the material that provides some level of influence when you enter this world. There are things you know that are built-in -- not just behaviors, but preferences that seem to have no roots in your current life.
Now with this consideration in mind, consider how all of these experiences & knowledge would culminate into a lens, or a window, as they must. This is easy to do. If you are conditioned to thinking you are "all that is of this life" then just expand your scope to consider you are "all that has come before" as well.
With this mind, then, let us consider: Why are you here? This article is not about why we live or why we experience but why you are here in this moment and not somewhere else. But the more important question is: why can't you go somewhere else?
"Somewhere else." What does that mean? Well, you can easily conceive a place "other than here" can't you? I don't mean your home versus the grocery store. I mean a place that seems "other" than your "whole conception of the universe."
And you say, well, there is space and perhaps other dimensions-yet-to-be-discovered and so on and yet even if we accept these explanations there remains one truth in all of this: wherever you go, there you are.
Our consciousness follows us wherever we go and provides the means by which we experience "the outside." So even if we move, or travel, can we have said to have gone anywhere at all? Not really. Your joys and foibles will follow you wherever you go. You cannot see past your own perceptions. What you see is always you, even if it is reflected off another.
