There is no need to try and get rid of fear.
If we experience fear because we mistake a rope for a snake we don't need to work on getting rid of the fear. The fear dissolves naturally when we no longer misperceive what actually is.
Psychological fear or anxiety comes from a misperception of what actually is - reality is not at all frightening or dissatisfying.
When we misperceive reality or what we are as fragmented and separate, we then feel that misperception as a sense of fear or discontent.
Thankfully, we have a built in GPS that consistently lets us know immediately when we have misperceived what is. Any sense of inner conflict is an indication of misperception and an opportunity to look again - directly.
Statements such as "There is no separation - we are all one" pop up in songs, movies, books and in conversations about life, spirituality or quantum physics - but rarely do those who voice these statements really consider how truly knowing that would impact their experience. And rarely do those who voice these statements seek to discover directly the truth of no separation.
It is all very simple. Instead of seeing things imagined, learn to see them as they are. When you can see everything as it is, you will also see yourself as you are. It is like cleansing a mirror. The same mirror that shows you the world as it is, will also show you your own face."
