There is no ticking matrix of “time” between these spheres because there is no such thing as time except as a concept in the mind of each individual observer. What’s most important to remember is that past, present, and future between these separate bubbles of reality have no meaning. So neither does any kind of death followed in time by rebirth. …
In short the very idea of death, or becoming nothing, is empty of meaning. … Because time doesn’t exist, there is no “after death” except the death of your physical body in someone else’s now. Everything is just nows. And because there’s no absolute self-existing space-time matrix for your energy to dissipate, it’s simply impossible to “go” anywhere. You will always be alive.
