In general, people all long for wealth, longevity or certain magical power. But, in the long run, it is very difficult to say whether these are really good for a practitioner or an ordinary individual. You are all familiar with the story of Devadatta. If he had not had supernatural power, he would not have committed two of the Five Great Offenses leading to the avici hell. He subjugated the king with his supernatural power, convincing the king of his might and to obey his words. Together, they committed a great deal of the offenses that led to the avici hell.
