The Universal Grid is a grid throughout the Universe. It looks three-dimensional but includes no time and no space. At each juncture is a mathematical two-number set, acting as co-ordinates. (I found out later that this is called a vector matrix.)
Everything within the grid is thought.
Travel within the grid, within the Universe, is by thought. Therefore it is instantaneous, involving no time and no space. Travel is from one set or sequence of coordinates to another.
For example, to travel from A to B, you may think of a place or time, or both, but that thought equates to a mathematical thought energy. So you travel from point A to point B via the coordinates.
