That is Buddha`s meaning of nirvana: to be free from life and death, to be free from desire. The moment you are free from all desires... remember, I repeat, ALL desires. The so-called religious, spiritual desires are included in it, nothing is excluded. All desires have to be dropped because every desire brings frustration, misery, boredom. If you succeed it brings boredom; if you fail it brings despair. If you are after money there are only two possibilities: either you will fail or you will succeed. If you succeed you will be bored with money.
