Quotes

 * Tell the Sultan, If you have not already realized that I am your co-equal in the work of ruling, then know that you have only attained to this power through my statesmanship and judgement. Does he not remember when his father was killed, and I assumed responsibility for the conduct of affairs and crushed the rebels who reared their heads, from his own family and from elsewhere. Tell him that the stability of that regal cap is bound up with this vizierial inkstand, and that the harmony of these two interests is the means of securing all objects soughts after and the ultimate cause of all objects gained. If ever I close up this inkstand, that royal power will topple.
