Worsening The Fear
We do not experience fear in the same way as an animal. If an antelope is being chased by a cheetah, the antelope has a primal or hereditary fear that tells it to run. But it is not thinking while it runs. We have the same hereditary fear in our DNA, but we add many layers to that fear when we give the power of a false mind/ego to continual worry. Do you notice how your fears are always related to the body --- losing your job, losing your house, someone not liking you, growing old, dying --- all are attached to an ego which fears that its "housing" will be destroyed in some way.
