OK then; There a three stages.
You clean up your inner sanctum ,which allows you to go deeper within without fear ,hate or any of the other energies that are from the second dimension . You meditate, then the undestructable part of you travels at over the light speed of the dimension that you are in without burning up and you will join up into a heavenly blissful state of unified consiousness.And that is only one level up!

The opposite way is much easier to reach but not worth the price of the fight to get out and back to here.

Pretty cool (I just made that up) Didn't I Bilbo .
