Can you reword/paraphrase this paragraph, please? "This can only be achieved after your beliefs and desires have been rigorously tested, which in the case of Santiago is his journey to achieve his personal legend. He is tested for his beliefs and his willpower at every turn of the page in the book and as these tests become harder, the progress he makes in terms of coming at peace with his heart becomes clear. After the point he gets robbed, Santiago cries about losing his sheep and his mind begins to think of "selling the stones (Urim and Thummim) and buying a return ticket (back to Andalusia", however, later as "he ran his fingers slowly over the stones, sensing their temperature and feeling their surface" his heart said "when you want something, the universe conspires in helping you to achieve it" and then continues his journey"
