Those without knowledge of the spirit soul are mad after materialistic activities, and they perform all kinds of sinful activities simply for sense gratification. According to Rsabhadeva, such activities are inauspicious because they force one to accept an abominable body in the next life. Everyone can experience that although we try to keep the body in a comfortable position, it is always giving pain and is subjected to the threefold miseries. Otherwise, why are there so many hospitals, welfare boards and insurance establishments? Actually, in this world there is no happiness. People are simply engaged trying to counteract unhappiness. Foolish people accept unhappiness as happiness; therefore the King of the Yavanas decided to attack such foolish people imperceptibly by old age, disease, and ultimately death. Of course, after death there must be birth; therefore Yavana-raja thought it wise to kill all the karmis through the agency of Kalakanya and thus try to make them aware that materialistic advancement is not actually advancement. Every living entity is a spiritual being, and consequently without spiritual advancement the human form of life is ruined.
