What does Ottaway mean when he says that Prince Mohammed "is trying to put these ultra conservative clerics back in their box"

When Prince Mohammed says that he 'is trying to put these ultra conservative clerics back in their box', he means that he will do everything possible to maintain these authorities within the limits of their environment without them affecting his domains. Prince Mohammed wants to implement his will and the conservatism of the clerics is putting his plans aside, something he isn't willing to allow.
