I think that this has something to do with Ki
As I tryed to expostulate on another thread/blog. It is an energy and why we assign positive and negative attractions to basically all things and experiences. The energy.
This is the thing that gives the molecules the attraction (so far they think) to combine into living beings.
Doesnt explain sentient beings, just the forms they take. Earth, man, woman, the heavens.
Intent leads Ki within the body systems. Connecting on a universal level is a whole other level.
Right now most of us are bound by the physical form and its limitations.
A partial physical explanation , very partial, anyway.
