To start with, fear is the main ingredient to live an unhappy life. It is true; all the fears come from the fear of death. It would be a simple reason not to fear, and that is because we are not created with fear but with love. Some people may strongly believe that we move to a different existence after death and for them will be no reason to fear death since the death of the body is not the end. For others who do not believe in the afterlife, fear should not be part of life because since we have no life after death, we must live this one happily. We hear many time the expression “We have only one life, live it fully” and that cannot happen if fear is present. Overall the reason that we live in fear is that we forgot to love. Love is the ingredient that glue together any human either a believer or a nonbeliever. Love is all that is and when we love we have no time to remember fear. If we want to let go of fear, we should awake and stop watching the fearful news or listen to our leaders talking about “what if.” Lao-Tzu said: “If you are depressed, you are living in the past. If you are anxious, you are living in the future. If you are at peace, you are living in the present.”
There is a movie called “Fearless” with Jeff Bridges which is an awakening call for someone who survived a plane crash. He stepped directly into the stage when fear was not present at all, and he realized that everything that kept him stuck in his life was fear based, including strawberry allergies for example. Everything fear is a creation of our minds. The problematic part of that awakening was that people around him could not understand him, and he became somehow anti-social. He refuses to lie because he couldn’t live a lie any longer. In the end, the character loses his ability and returns to his original life proved by the fact that he was about to die by eating a strawberry.

We all can be fearless if we ignore that part of the mind we call ego and come to realize that fear is useless and dangerous for living a happy, healthy life.
