Darkish Aura?, What's it mean and how to fix it... Options

So someone I know who happens to be able to see aura's offhandedly told me of the gray darkish color surrounding my person. Upon further investigation of what a darker colored aura denotes, I wasn't very satisfied with the descriptions. There are positive and negative descriptions of the color as well as different ideas concerning what it's meant to indicate in the first place. Perhaps someone can explain the idea behind an "aura" and its color and what it might mean to possess a grayish one?

Something that I read that did cause some minor thought within me though I admit wasn't surprising was a description of blocked energies associated with the said aura color. I wondered if perhaps this could be an explanation towards my failed attempts at things like meditation, astral projection, etc. I used to think persistent was the key to my dilemma however that's come to another unfortunate close. If I can safely determine that my failures were even in part due to blocked energies and everything associated with such a status, how might I overcome this obstacle and finally be able to move on and away from this prolonged rut I've managed to remain in.

As Mchawi has mentioned, be wary of what people tell you about yourself. Perhaps it is true, but I have known people to make a pronouncement on someone that was more inflated ego than truth. Generally a grayish energy denotes depression by the way, rather than being an indicator of any terminal illness. I thought that you should know that for your peace of mind. We all have areas in which our energy doesn't flow as well as it should. We all have our blockages. But in any case, if you feel that it is true here is a suggestion. You have mentioned that meditation and some other things you hadn't had much success in. Perhaps you are more the doer type than the sitting meditation type. There are a number of Qigong exercises that are active. Perhaps you are more of a physical kind of person, and these kinds of Qigong exercises may suit you better than sitting meditation. Plus it will help work through those blockages and get your energy flowing better.

I have recently come to like You Tube because it is so accessable, and unlike with books, you can see exactly how the exercise is done. You can do the exercise along with the video. The first one at the top is Gathering Heaven Qi, a good basic exercise. There is a fair selection of basic exercises online.

I hope that helps.
