This diagram shows (for universes below the Infinite-life-universe) at which point in a universe, the next universe down was built.
This diagram does not attempt to illustrate the different rates of time in each universe (each universe flows more slowly than the one above). Each flow of time applies only within the relevant universe Playing-field.
The Infinite-Life universe has a time-line which consists of multiply-connected loops of different sizes. Time doesn’t apply in the same way senior to the Infinite-Life universe. The fact that our current position on the Physical-universe time-track is very near the end, means that almost all beings here at this time also have presence in all 3 lower universes.
