You can dwell, psychologically, in the desired state. So, although you may not be able to tread physically upon a state or city, you can always tread psychologically upon any desired state. By treading psychologically, I mean that you can now, this moment, close your eyes and after visualizing or imagining a place or state other than your present one, actually FEEL that you are now in such a place or state. You can feel this condition to be so real that upon opening your eyes you are amazed to find that you are not physically there.
