The foundation for the eradication of fear has to do with believing in your own wholeness. To the degree that you know and can feel your own wholeness, you can live without fear and self-protection. This is because the wholeness in you is not dependent on anybody else. There is nobody else who can touch it.
As long as we perceive ourselves as separate from others and needing to protect and defend ourselves from them, we will not be able to act in the way we would like to. We will be inconsistent. We will wish for somebody else to do the job. We will wish for it to magically happen.
