You cannot conquer fear. Fearlessness means intelligence to live the intense fear without directing it towards any object. When there is no object to be afraid of, the intense fear will give such an intense relaxation and peace.
Fear is a powerful energy which gives a deep relaxation, a deep centeredness. The fear center is the rejuvenation center.
Fearlessness is not suppressing fear.
For example, when you are afraid to cross a dark area in the night, you start thinking of and repeating god’s name. Because of fear, god’s name will be topmost in your mind! You feel that you don’t have fear because your inner chatter is engaged in something else! When you engage your inner chatter in something else, you feel that you are out of fear. But you have only diverted your attention, you haven’t solved the problem completely.
There is a saying, ‘When a cat drinks milk, it will close its eyes tight and think that the whole world has become dark, and therefore, nobody can see it!’ Understand, you also do the same thing when you don’t pay attention to the fear, and then believe that the fear has disappeared.
Fearlessness does not mean non-existence of fear. It means the fear is there, but you have tremendous energy or courage to live with it and face it. Fearlessness means having the energy or the courage to live even with the maximum fear. It is going beyond that fear and being neither attached to nor detached from the fear.
One more important thing you should know is fear is part of the nature of life.
