When you are not sure that you are on the right path, then call on the Light from with in to shine on the path that you are to follow. You feel the light in your heart and body. Your cells recognize the path from the light of your soul.
When people do bad things, then they are not feeling the light, and they are wandering into the dark places. They have lost the clarity of purpose.
When things are turning around for you, let the light shine even stronger than when you were looking for your path. Perhaps your light will be a lighthouse for someone else.
