I just had an interesting picture on my mind. Imagine all people in this world initially walk through barren and desolate land for the most part of their lifetime. But sometimes some of them suddenly see an oasis before their eyes. They can hardly believe that they now can leave the wilderness they were in for a very long time and sparks of hope begin to take root inside their hearts. However, alas, as they come closer and closer, they realize that what they had seen within their reach seemed to be only a Fata Morgana since it was gone as soon as they wanted to take possession of it. Grievously disappointed and discouraged they find themselves forced to continue on their journey through the desert, but they cannot forget the beauty of the place they would see before being able to arrive there.
