Fear is an outcome of long-collected problems unsolved. When once a person looks his own problem in the face he gets an insight into the cause of fear, and as in the sun many germs are destroyed so the germs of fear are destroyed by the light of intelligence.
Fear comes from weakness to face the consequences of one's condition, attitude and deeds. Once a person has solved the problem how he will meet the consequences the fear is done with. The best way of getting over the fear of swallowing a bitter pill is to swallow the bitter pill and to experience by it that it is not more bitter than it is.
Fear comes also by being too cautious for one's health, morals and reputation.
Also by being too considerate of the feelings of those one loves, and too regardful of those under whose influence one is.
Also by taking too much to heart what others say. Fear very often remains in the heart of man in the guise of virtues, and very often a timid one is taken for a righteous one. But the timorous well-doer is worse than a fearless sinner.

The best practice one can make is to speak with oneself, with one's own fear; to dispute with it, and to root out the reasons on whose foundations it rests. What generally happens is that all things one fears, one fears even to think of them.

But the solution of getting above fear lies in analyzing the cause of the fear and so making it non-existent.

Man by nature possesses a tremendous power hidden in his heart, the power which waits constantly to become manifest. This power is hidden by fear. The day when fear disappears this latent power manifests to view.
