Thanks for the replies guys.
I understand that everyone is connected to the force. I guess i'm talking about increasing a "non-force-sensitive" to the point where they could train to become a Jedi/SIth/
I know there have been Jedi who completely cut themselves off from the force (can't remember her name from the Revan Books for example) but I can't think of an example of someone who isn't force sensitive enough for training... Kinda like a success from the Rakata experiments to regain their force sensitivity after they lost it.
Anything?`
EDIT: Just read the last post mentioning the Scepter of Ragnos. Stuff like that is EXACTLY what i'm looking for. Anyone know of anything else?
