Gambling is also an art. Ksatriyas are allowed to exhibit talent in this art of gambling. By the grace of Krsna, the Pandavas lost everything by gambling and were deprived of their kingdom, wife, family and home because they were not expert in the gambling art. In other words, a devotee may not be expert in materialistic activities. It is therefore advised in the sastra that materialistic activities are not at all suitable for the living entities, especially the devotees. A devotee should therefore be satisfied to eat whatever is sent as prasada by the Supreme Lord. A devotee remains pure because he does not take to sinful activities such as gambling, intoxication, meat-eating and illicit sex.
