Most are unwilling to accept it because of where they are in their lesson. Spiritual growth draws us closer to that lesson by constantly mirroring that denial in our world. The guidance appears when we choose to see it and accept it. The projected nature of our awareness makes it appear to be so. The body is an agent of form.
Emotion is an agent of feeling.
Mind is an agent of idea. Spirit is an agent of value. Still, these dimensions of freedom communicate their aspects of reality to us. We are guided towards complete freedom by aligning our perception of how these work together. It happens continuously, but we simply choose to believe the projections over our inner reality.
