A Course in Miracles Topic - Time and Space

Time and space are ideas that don't exist beyond perception and therefore are part of the dream.

...you think you live in space, where concepts such as "up" and "down" are meaningful. Ultimately, space is as meaningless as time. Both are merely beliefs.                   T-1.VI.3:3-6.

...before the separation, ... belief in space and time did not exist.               T-2.II.4:4.

Your holiness reverses all the laws of the world. It is beyond every restriction of time, space, distance and limits of any kind. Your holiness is totally unlimited in its power because it establishes you as a Son of God, at one with the Mind of his Creator. W-38.1:1-3. (Lesson 38: “There is nothing my holiness cannot do”)
