If you concentrate and watch silently, you can know what is going to happen to you in the future, but usually your mind remains busy in the material world. Everything happens in the subtle world long before it takes place externally.
The purpose of fear is to lead you to question and understand why you have that fear in the first place. As you examine your fears, you will learn that all your fears are somehow false and based on misunderstandings. There is no truth or reality to your fears. Many fears remain buried within you, and you never really examine them, so you remain at their mercy.
