The illusion holds power over you when you are not able to remember that you are a powerful spirit that has taken on the physical experience for the purpose of learning.
You cannot find your soul with your mind, you must use your heart. You must know what you are feeling. If you don't know what you are feeling, you will create unconsciously. If you are unconscious of an aspect of yourself; if it operates outside your field of awareness, that aspect has power over you.
