The story of Aladdin illustrates this truth. Aladdin could only attain to the princess when he first obtained the lamp or candle which she desired. He goes out into the world but cannot find the candle there. So he goes into the forest, and there he meets with someone who is able to show him the way to reach it. This person cannot himself give it to him. This means that just emotion does not suffice to bring it. No, he is told to go to a certain mountain, and repeat certain words which will cause the side of the mountain to open. He does this, and the caves open up, but when he is within them he begins to suffocate because there is no air. Nevertheless he goes on into the caverns perseveringly, and in time he comes upon the lantern.
