What is the difference between the two planets / their inhabitants. Mortis is a conduit of the force and home to a family of force-beings, and the other planet was supposedly the origin of the midi-chlorians / the force? And home to a five immortal force-beings. I realize the Ones are still tangible mortal beings, whereas the priestesses were immortal, formless and already at one with the force, but they are both "force beings" with a connection to the force beyond the norm by regular mortal beings. Also on another note, these five beings were already existing within the force itself and had achieved the ability to retain their identity after death, and dwelled on the life giving planet, but how did they achieve that, i'm assuming someone/thing must have taught them since they say they had achieved this power. And how was Qui-Gon able to learn this after dying, when Yoda had to physically travel to a real physical location to learn?
