Energy types.. Jing, "fifth force", anyone know?

[Tom]

Please let me simplify things for you. There is energy that you feel in yourself and have direct access to you. If you want to label it "chi" or "ki" or "prana" or "jing" or just plain "energy" that will not change its nature. You do not need words to feel your energy, to make use of it, and to increase it.  Whatever energy you have in you, this is the most powerful sort there is. When you read articles, books, web sites, and so on you are reading the experiences of other people put into words for the purpose of communication. It is still necessary for you to have the experiences for that communication to be completed. When this is done you can drop the words. No, there is no way to be certain that you are having the same experience which is being described. That can't actually be precisely done. Fortunately, the only authority you need is your own experience and judgment. What else do you need?

I've read articles on several different types of energy, including jing, auras, fifth force.. Could someone familiar with these give their opinion on which one seems to be the strongest/most useful type to raise and control and maybe explain a bit about them?
