From a metaphorical stance, the fisherman represents any individual with a life ambition- being it work or relationship related.
Only when his basket is filled can he be greeted with a smile
At this point, the individual achieves what he or she aimed for and reacts to such fulfillment with signs of relief and satisfaction.
I say a prayer for the fishermen and their hooks may their basket be filled for their homecoming...
I believe this is a prayer for individuals with life goals. It is our utmost desire that we accomplish our targets and exceed expectation. If one person wins, we all win.
