Perhaps you are searching for your purpose in life.  To grasp your place in the world is to comprehend who you are and where you fit.  What can be grasped mentally is intelligible, clear, explicit, positive, definite, precise.  The Wheel of Fortune represents a new cycle of unchanging reality in which the laws of "cause and effect " are always operative.  When we understand the natural rhythm of nature, we see a parallel towards our own lives.  Each season in the yearly cycle has a definite purpose.  Attune yourself to the rhythm of life and know that there is a time to plant, a time to wait and a time to reap the harvest.  If you find that you continually make the same mistakes, you are not learning from your experiences.  If you do not plant the right seeds, you will not get the results you want.  Learn to be patient, let go of your fears and ask God for guidance.  Never go to sleep depressed.  Tomorrow is a new day.
