Hi Paul,
You asked about defining terms for lightworker/darkworker/etc. Julia suggests simply "negative polarity" and "positive polarity", based on the -10 to 10 scale, where people who are not polarized are 0.
To explain further what being polarized really means, you have to understand how people set goals. The following is based on my experience reading other people and understanding the fundamental differences between negatively-polarized and positively-polarized people.
Every person in this world carries around a statement or picture in their heart that encompasses their main life goal. Normally when I read people I visualize it as a picture and then transform that into a statement that makes sense for them. It's usually quite simple. For instance, mine is "I want to help other people." This defines most of the interactions in my life, most of the goals I set, and most of what really makes me happy. (The key here is if that person is working in harmony with this goal, which I call their "heart goal", they are happy.) The guy I am dating right now has a heart goal of "I want to be loved." The picture in his heart that he carries along with this is his family loving him. My picture is me helping other people become enlightened. When I tell people the picture I see, along with my translation of their heart goal, they get it on a really fundamental level. The two goals above align significantly with positive polarization.
On the other hand, I did date recently a guy who was negatively polarized. His heart goal took me completely by surprise! The picture I saw was him standing on top of a mountain, by himself, proudly looking around and surveying the land, and knowing that he had climbed it all by himself. But there was no one else there, and that was what shocked me most, because most people's heart goals have other people in them. I explained this to him and he nodded, saying "I don't need anyone else." I said, "Isn't it lonely at the top of your mountain?" and he said "No, I'm happy." And oddly enough, he was. That's how negative polarization works. It is defined as being interlinked with a heart goal that doesn't need
or want anyone else in the picture. If people are there -- even if you're married -- you're using those people to draw energy toward you and help you out, not because you particularly need to help them. It's not in and of itself "evil", because you aren't trying to hurt them. You just use them for what you need, and the people in your life get that, and are okay with it.
This negative-polarized person that I described is right now starting a business that will help other businesses become more environmentally friendly. I wish him the best, because he will help a lot of businesses and the environment if his business succeeds. Why would he help other businesses become more environmentally friendly? "Simple," he told me. "It'll make me rich!" He knows that being environmentally friendly is very "in" right now, and he's going to start a business to capitalize on that wave.
And that's how negatively-polarized people view the world.
So you want to polarize?
Set goals that are bigger than yourself, and work to achieve them, and by necessity, you will polarize. Yep, it's that simple. The act of setting goals in and of itself will not cause you to polarize, but if you want to
achieve those goals, you must polarize. No polarization is "good" or "bad" as long as you don't exploit yourself (lightworker syndrome) or exploit others (darkworker syndrome.)
Examples of specific goals that will force you to polarize to achieve them can be found in my post
Polarity and goal achievement.
Hope this helps.
