Imagine the Sun as “God and the spirit world” and your shadow as “worldly desires”. If you turn your back to the Sun your shadow is in front of you. No matter how hard you chase after your shadow you will never get to it. It is always a step ahead. If you turn around and walk towards the Sun, immediately your shadow will follow you. Now the world is chasing you instead of you chasing it. Walk towards the Sun, walk towards God. Make God your focal point and the material world will follow you.
