These are the two desires which we hold. It is when we do not know the manner in which to attain these two desires that sometimes the joy of one part of our being takes away the peace of the other; or the peace of one part of our life takes away the joy of the other part of our being. It is when man once knows this that he is able really to master himself, to manage his life's affairs as he wishes, to have a better idea of what is right and what is wrong, and of what is sin and what is virtue.
