Scientists calculated mathematically that the Universe is either, a smooth ball shape, or a lumpy ball, or a saddle shape. In the Aluna Mirror-Worlds one is shown that the saddle shape is correct. It the Pringle shape.
The Mobius strip (see below) is like the saddle shape, it describes eternity looping back on itself. One of the practices I use is to trace the loop in the air with my finger many times a day, especially at night. It grants you protection to link to eternity in that way.
