"All the miseries and discontents of life he traces to insatiable selfishness. Suffering, he teaches, is due to the craving individuality, to the torment of greedy desire. Until a man has overcome every sort of personal craving his life is trouble and his end sorrow. There are three principal forms the craving of life takes, and all are evil. The first is the desire to gratify the senses, sensuousness. The second is the desire for personal immortality. The third is the desire for prosperity, worldliness. All these must be overcome — that is to say, a man must no longer be living for himself — before life can become serene. But when they are indeed overcome and no longer rule a man's life, when the first personal pronoun has vanished from his private thoughts, then he has reached the higher wisdom, Nirvana, serenity of soul. For Nirvana does not mean, as many people wrongly believe, extinction, but the extinction of the futile personal aims that necessarily make life base or pitiful or dreadful. Now here, surely we have the completest analysis of the problem of the soul's peace. Every religion that is worth the name, every philosophy, warns us to lose ourselves in something greater than ourselves."
