Don Quixote - pg. 582

"O thou, more fortunate than all those who live on the face of the earth, for thou dost not envy nor art thoou envied, and thou sleepest with a tranquil spirit, and thou art not pursued by enchanters, nor art thou alarmed by enchantments! Thou sleepest, I say it again and shall say it a hundred times more, without jealousy of thy lady keeping thee continually awake, nor thoughts of how to pay the debts thou owest, nor what thou must do to feed thyself and thy small, anguished family for another day. Ambition doth not disturb thee, nor doth the vain pomp of the world trouble thee, for the limits of thy desires extendeth not beyond caring for thy donkey; thou hast placed care for thine own person on my shoulders, a weight and a burden that nature and custom hath given to masters. The servant sleepeth, and the master standeth watch, thinking of how he may sustain him, and improve him, and grant him favors. The anguish of seeing the sky turning to bronze and not giving succor to the earth with needed dew doth not afflict the servant but the master, who must sustain in barrenness and hunger the one who served in fertiliy and plenty."
