"2. We have already seen that the Cause of Sorrow is always desire. If a man has no desires, if he is not striving for place or power or wealth, then he is equally tranquil whether the wealth or position comes or whether it goes. He remains unruffled and serene because he does not care. Being human, he will of course wish for this or that, but always mildly and gently, so that he does not allow himself to be disturbed..."
