Time and space are just projections of your consciousness.
The fear is simply because you are not living with life, You are living in your mind.
Generally, people who are not self-realized are full of themselves. One who is self-realized sees that the whole world is full of one.
Life happens from within. How aware you are of it, decides the quality of your body, your mind, and your experience of life.
Life is not outside of you. You are life.
Consciousness is not a bunch of thoughts or a certain level of understanding. Consciousness is a dimension that is beyond our physicality.
