Using the Energy of Fear
One may ignore, deny, or use the energy of fear to awaken. Ignoring and denying are short-term solutions.
Siddhartha, before he became Buddha, was confronted with four messengers - old age, sickness, death, and the yogi. We meet the first three as natural parts of life. Some are fortunate enough to meet the fourth and get the message that one can work on him/herself to awaken to be free from fear.
Don't let fear take over. Fully experience fear while not being driven by it into a freeze, fight, or flight reaction. Use the fear as a motivator for positive action while taking on a new relationship with the fear and its causes.
Fear and Clinging
The root cause of fear (as with all unpleasant emotions) is attachment. Attached to pleasant outcomes, when thoughts of not getting what we want are strong, we experience fear. Hope breeds fear if one is attached to what is hoped for.
That word "attached" is the key. Accept what comes with an attitude of "It is what it is" and the root of fear is cut. Cling to a fixed idea of the future and fear will arise as an obstacle to getting what you want. Ignore the reality that you might not get what you want, and you lose the opportunity to overcome obstacles to success. Give in to the fear of failure and you won't try.
Acceptance and non-attachment enable accomplishment by eliminating the unnecessary energy drain of clinging to wanting things to be different than they can be.
You cannot change the past or present. You can change your attitude about them. You may be able to influence the future to get what you want.
Warriors cut the root of fear by accepting the reality of their own death and overcoming attachment to their ego self - their body, intellect, and personality. Without the fear of death and with the acceptance of defeat they can more likely succeed. They can overcome the negative mental states that cloud the mind and get in the way.
Until the root is cut, put mindfulness to work. Change the scary-future story (after all, it is just a story). Cultivate a view that recognizes the reality of impermanence, uncertainty, and a continuous process in which everything is changing moment to moment. Learn to thrive in free fall with no solid ground underfoot, no walls, and no roof. Find the indestructible calm center, beyond hope and fear and from there proactively do what can be done.
Short of all that is medication, which if skillfully used, can help temporarily. You can anesthetize, but the anesthesia will wear off and have unpleasant side effects.
Cutting the roots of anxiety is neither easy nor quick. It requires effort, courage, perseverance, skillful use of meditation, contemplation, and psychological practices, and a deep experiential understanding of how things are.
"It is said that before entering the sea
a river trembles with fear.
She looks back at the path she has traveled,
from the peaks of the mountains,
the long winding road crossing forests and villages.
And in front of her,
she sees an ocean so vast,
that to enter there seems nothing more than to disappear forever.
But there is no other way.
The river cannot go back.
Nobody can go back.
To go back is impossible in existence.
The river needs to take the risk
of entering the ocean
because only then will fear disappear,
because that’s where the river will know
it’s not about disappearing into the ocean,
but of becoming the ocean."
