Parsifal is a myth about a young man who seeks to answer a riddle presented by the Fisher King in Grail Castle. If he answers correctly he will win the right to marry the daughter of the king, Fleur Blanche. The question is, "who does the grail serve?" He hesitates in his answer, becomes bored since he can't marry the princess and leaves the castle to find his bliss. after many years he returns and because he is wiser now, he knows the correct answer and is able to marry the princess. There are several points to the story; 1.)wisdom comes with age and experience 2.) that which we seek is often right in front of us.
That's a real oversimplification of the story.
