A question about what is illusion
In this sense your fears are illusions because a change of mind brings the rays of light which shine through the fears, dissipating them, making them transparent and leaving in their place the certainty of each moment. There and only there is the reality in the changing movement of the eternal as we reflect (enter vantage point upon vantage point) on these changes causing indeed the very changes we are reflecting upon.
That is why in an instant a person's life can undergo dramatic changes as your mind changes, adjusts and recognizes now the eternal being that is becoming. What exists is I AM in and through everything. When your identity rests there every thing is possible. Using this analogy the creator rests within the soul of the created. Every attempt to find the creator without is meaningless. It's like looking for your glasses when they are on top of your head. You take it with you wherever you go.
