What I'm saying is that the "center" is not necessary in the "middle" - for example you have "cultural center", not "cultural middle". The thing is, center is something that gives you reference, hence balance, while middle is just a point (you even said both of those, center=finding balance, mid-point).
Therefore you should be looking out for the center, not for the middle to find balance.
Although, center often happens to be somewhere around the middle, so I get the simplifications :)
Consider this: you not only can't be in a same place ever again, but also that place will change, since it will be changed by you "visiting" it. What's more you will never be able to repeat that as it happened - in a given time with the given past - no matter what you do that place, time and past will be affecting it. Even time travel can't do that (since you will know about the past, which will be still affecting you).
Infinite complexity of the world once again... :D
Just reading stuff about galaxies gives you this vibe of unreality. As I said, we talk about things like that and yet grass behind the window still looks the same :)
