You cannot teleport your physical body from one location to another. It is impossible. If you were to search for some of these things before you ask, you would find questions almost the exact same as yours that have already been answered and save yourself the wait.
Now, as I said you cannot teleport your physical body, however you can Astral project. Astral projection is where you project your astral body onto the astral plane, but it is not really the same as physically being there. The astral plane is best explained to a newcomer as another dimensions of sorts, it appears the same as the physical, but only astral beings can exist there. It is said that the workings of magick manifest on the astral plane before they can influence the physical.
Astral projection is not easy in any way. It takes lots and lots of practice. You have to be very well accomplished at meditation before you can attempt to separate the astral and physical bodies. I would suggest that before dabbling in astral projection you study magick and your chosen tradition more so as to better understand the inner working of the astral plane and anything you may encounter on the astral plane.
