There is a clear distinction between fear created as a tool for manipulation and fear as a warning for survival. Fear is what helps us survive when we realize that major changes are required to achieve survival. In the first fear is used to destroy rational thought and trigger violent emotions. In the second fear needs to be managed by all of us, not as an irrational emotion, but as something that we accept and understand.
This is a rather useful thought on this that I just ran across today:
Fear is not the enemy — it is nature’s protector; it only becomes troublesome when it oversteps its bounds. In order to deal with fear we must take a fundamentally noncontentious attitude toward it, so it’s not held as “My big fear problem” but rather “Here is fear that has come to visit.” Once we take this attitude, we can begin to work with fear.
— Amaro Bhikkhu, “Inviting Fear”
