The problem with fear is fearing it. Fear on its own is just fear, arising & ceasing just like everything else.
Only when fear is feared does it escalate/proliferate: i.e.. when it is subjective. But when objectified it exhibits the Dhamma, i.e.. three characteristics, internal & external, cause & effect, etc.: and as such, a gateway to Nibbana.
There is fear & there is the knowing of fear. Thus the middle way is in being with the knowing of fear.
