and why multiple incarnations (and there is more "to it" than one body recycles into a new body) can and do "happen"
concurrency is not (as well) strictly linear . . . basically, you time share physicality with a higher consciousness "source" and the higher source is actually YOU, regardless of the incarnate features of individual "lives on Earth"
translated; your consciousness is the stream the feeds the individual sprouts
and the consciousness is "consistent"; this conscious "consistency" is what actually reincarnates
made even funkier in that this consciousness never actually "inhabits" a physical body
may sound weird -- but the conscious "soul essence" permeates the body
and the essence is also the "cloud data source"
for the individual incarnation
