REALIZATION OVERCOMES FEAR 
The biggest problem that we face is that we are ignorant of our ignorance. We don’t realize the difference between the facts and fake information. We continue to live our life without realizing the truth. A very few people go on a quest. They are the ones who overcome fear as they are enlightened with the truth.
What is this quest that we are talking about? Most human beings live and die without even finding out who we are and why we are here. We think we are the body and the mind. Therefore, we suffer. We don’t go in quest of the truth and thus we live and die in ignorance and fear takes control of our life. Prince Siddhartha, who became the Buddha went on a quest and realized the truth about life and with it, he was able to overcome fear.
If we live spiritually, there is no need to fear. We know nothing belongs to us, but the ego lives with the illusion that this is mine. We chase wealth and victory and we constantly live in fear. First, we are stressed whether we will achieve our aspirations or not. And if we achieve them, then we fear the loss of our possessions.
The Buddha created a new doctrine that taught people to live with his Four Noble Truths and follow the Eight-Fold Path.
