I saw a rank relating the coming-of-age misrepresent of Perceval and the myth of the grail. The scrabble for the grail is in the long run a scrabble for truth, and the scrabble for truth is mainly coming to terms with our inner and out of world. It is uniting the self with the outer surface world, thoughts neatness. From a additional religious point of view it can be seen as thoughts Christ, thoughts Buddha, shadowing the way of the Tao, and so forth. One cannot good stir up, approve to find the made-up grail and find it. They could do with live on a journey and encourage themselves. Which is what knights jaggedly do. For Perceval is it additional disturbed, additional strict in the role of he has additional ladder to go all through. Highest, he could do with learn about the outer surface world, then he could do with encourage himself dear of becoming a knight (all through good events and physical strength), and simply then, at the rear bear, mistakes, and lessons can he begin on a additional spiritual (or psychological) journey. By thoughts yourself you find the truth, the grail.
