"The ceaseless efforts to banish suffering achieve nothing more than a change in its form. This is essentially want, lack, care for the maintenance of life. If, which is very difficult, we have succeeded in removing pain in this form, it at once appears on the scene in a thousand others, varying according to age and circumstances, such as sexual impulse, passionate love, jealousy, envy, hatred, anxiety, ambition, avarice, sickness, and so on. Finally, if it cannot find entry in any other shape, it comes in the sad, grey garment of weariness, satiety, and boredom, against which many different attempts are made. Even if we ultimately succeed in driving these away, it will hardly be done without letting pain in again in one of the previous forms, and thus starting the dance once more at the beginning; for every human life is tossed backwards and forwards between pain and boredom."
