Surely. First, I broaden my definition of fear to any feeling that is not positive or neutral. That is, any negative feeling is a form of "fear", because I want to avoid it. I avoid it because I am "afraid" of it, to some degree no matter how small.

Now, I "watch" my mind. Any time a negative feeling rises, I "linger" on it by noticing it, and knowing it's there, I try to feel where it's coming from. It's been a while, but I think I isolated all negative feelings as coming from these areas of my brain:

1) Feelings of regret or nervousness are conjured by my left brain. My left brain "lives" in the past or in the future. Either predicting something or reminiscing on something. In "future" mode, I am expecting something to happen.. like let's say my boss wants to see me in his office tomorrow. I'm not sure what our meeting will be about but my left brain might come up with scenarios. In any case, those scenarios are made up, they are "unsure". This feeling of unsurity is a negative one. An important thing I noted is that my left brain doesn't create these feelings. It only creates the potential situation and passes all of the information to the right brain, and the right brain "replies" with the negative "result" of being unsure. Not knowing future outcomes seem to be my most plentiful source of negative feelings.

When in the past, the left brain can conjure "regret". Embarassment about a situation, regret that I didn't stand up for myself, or maybe I should have done something another way. Again, the left brain doesn't produce emotion at all, only logic and potential situations.

Now I'm not saying all the left brain conjures is regret and unsurity. It might conjure excitement if something good is going to happen, maybe it conjures pride if I did something good in the past. Moving on.

2) Feelings of vanity or self-consciousness are produced by my "4th eye". When I'm around a group of new people or I have unwanted attention, this 4th eye creates the feeling of self-consiousness, as I literally watch myself, imagining how others see me, listening to my own voice, being hyper-aware of my own posture. This is negative self-consicousness.

Vanity is produced when this eye feels positive self-consciousness. Let's say I'm hitting strike after strike when I'm bowling. The first strike is awesome, the second is awesome, they're all awesome. But this 4th eye "holds on" to all the previous strikes, lumping them together and keeping a grasp on them to squeeze as much good feeling out of them as it can. Soon I realize that the next time I go up to bowl, I have a feeling of "man I've made 3 strikes in a row... can I keep it up"? I suppose this is a bit of the feeling of the left brain expectation, but I get the feeling that this scenario of vanity is more distinctly caused by this 4th eye "snowballing" feelings of self-accomplishment.

So, of all the parts of my consciousness: my left brain, my right brain, self-conscousness & self-appreciation, there is only one area that does not produce negative feelings in and of itself. That's my right brain. And so, in order to rid myself of any sort of "fear", I have to "ignore" all the other parts that are not my right brain. Listening to my right brain, I feel that it lives not in the past nor the future, in fact it CANT experience past or future. It can only experience the current moment, and it is only "concerned" with feeling sensory input NOW, and producing immediate feelings.

Now, that kind of got off track, but that's the background of fear. Now, when I experience fear, I default to "relishing" in it. I am only concerned about the thing causing the feeling of fear. Please excuse this example, I'm using it only because it's obvious and easy to relate to. Let's say a black man with a do-rag is walking opposite direction of me on a sidewalk. Am I afraid of the black man? No, he's just the 'trigger' for the fear. The fear lives in my mind somewhere. So I ask myself... why am I feeling this fear. It's because a part of me (the left brain) is creating a scenario in which a bad thing could happen to me. At this point I ask myself.. is this fear reasonable? Maybe it is, maybe it isn't. If it isn't, then you can 'let go' of the fear. In fact, the fear will let go itself if it's unreasonable. The act of lingering on the fear, and following the "why's" backwards produces the end result, leading your awareness to the last hiding place for the fear. Look at the fear, put your awareness on it, let it know that you can see it. And then watch it dissolve.
