The sixth inquiry is: The Zohar (Tazria 40) states that man is the center of reality and that all of the upper worlds as well as all of this material world and all it contains were created for the sake of man. The Talmud states (Sanhedrin 37a) that a person must believe that the world was created for him. It seems difficult to understand that all of creation is for the sake of insignificant man, who is less than a hairsbreadth compared to the whole of existence. This becomes even more difficult to understand when man is compared to the infinite and lofty upper worlds. Why would God bother to create all of them for man?! And what does man need with all of this?!
