Answer: hello your question are based on the excerpt <em>The Alchemist </em>
He believes Santiago shouldn't have to clean just to eat
To feed the hungry as commanded by the Koran
He feels he wont have anything to live for again
Cleansing of his heart of bad thoughts and
building of a display case outside the shop to attract customers
Explanation:
The Crystal merchant fed Santiago because he believes he shouldn't have to clean before he can feed him and moreover the Koran commands
The obligation the Crystal merchant desires to do is to feed the hungry as commanded by the Koran
He doesn't go because he feels he would lose everything ( i.e. he wont have anything to live for )
The two new ideas suggested by Santiago are : Cleansing of his heart of bad thoughts and building of a display case outside the shop to attract customers
