My ego believes that asking this question will help me to find the cause of it, and that I might then be able to fix the problem.
But what's going to happen is, I'll start searching for causes. If I seem to find a possible cause, it's going to tell me "the fear is caused by..." But no matter what it says, it is not really the truth.
Every cause of fear that we think is the cause of it, is not the cause. Fear is not caused by something happening to us. But it seems to arise at the same time as perceiving there's something happening to us, or threatening to happen.
If this.... then that's going to happen. If I do this.... that might happen. But it's still me perceiving and imagining the situation and creating the fear.
I'll think the fear is caused by the 'thing' that threatens me, but the thing that threatens me is not really the cause of fear. So long as I perceive that there is a threat, there WILL be fear. I can't keep the perception of the threat and get rid of the fear. I have to change my perception.
The reason I am afraid is because I am choosing to be afraid. I am choosing fear by choosing to see myself victimized and threatened. I THEN perceive the threat and experience the fear, but neither is the cause of each other.
I am afraid because I am using fear to deny God. I am afraid because I believe fear is a trustworthy guide that tells me the truth. I'm afraid because I want to invent a reason not to be happy and awake. I'm afraid because it allows me to have an ego.
It would seem fear is stopping me from doing what I want, but really fear is an excuse, a made-up reason why not. Without making it real, or believing in the threat being true, I couldn't be afraid, and then there'd be no reason not to.
Fear is part of the device for separation.
I still feel compelled to find out "why" I am afraid, but I sense that the "reason" will be an illusion, and that there will be deeper dynamics than just that I am afraid. Ultimately it cannot be true that I am afraid, it can only be an illusion.
As Jesus says, we only become afraid when we think that illusions are real, and that God is not on our side. I must be incorrectly perceiving an illusion as real truth, or wanting it to be truth, otherwise there'd be no grounds for fear. If nothing has really gone wrong and nothing real can be threatened, there is no basis for fear.
I need to forgive myself for my self-made fear and undo the need for it.
