Foolish materialistic people collect money and steal from other thieves, but they cannot keep it. In any case, it must be spent. One person cheats another, and another person cheats someone else; therefore the best way to possess Laksmi is to keep her by the side of Narayana. This is the point of the Krishna consciousness movement. We worship Laksmi (Radharani) along with Narayana (Krishna). We collect money from various sources, but that money does not belong to anyone but to God(Laksmi-Narayana). If money is utilized in the service of Laksmi-Narayana, the devotee automatically lives in an opulent way. However, if one wants to enjoy Laksmi the way Ravana did, he will be vanquished by the laws of nature, and whatever few possessions he has will be taken away. Finally death will take everything away, and death is the representative of God.
