The opulence of a devotee is different from that of a materialist

The opulences offered by the Supreme Personality of Godhead are not to be compared to the opulences obtained by karma-kanda. In other words, if a devotee becomes very opulent, it is to be understood that his opulence is a gift of the Supreme Personality of Godhead. Such opulence will never be vanquished, whereas the opulence achieved by one’s fruitive activity may be vanquished at any moment.
