When the modes of passion and ignorance increase in human society, giving rise to unnecessary economic development, the result is that people become involved with wine, women and gambling. Then, being mad, they maintain big slaughterhouses or occasionally go on pleasure excursions to kill animals. Forgetting that however one may try to maintain the body, the body is subject to birth, death, old age and disease, such foolish rascals engage in sinful activities, one after another. Being duskrtis, they completely forget the existence of the supreme controller, who is sitting within the core of everyones heart (isvarah sarva-bhutanam hrd-dese rjuna tisthati [Bg. 18.61]). That supreme controller is observing every bit of ones activity, and He rewards or punishes everyone by giving one a suitable body made by material nature (bhramayan sarva-bhutani yantrarudhani mayaya [Bg. 18.61]). In this way, sinful persons automatically receive punishment in different types of bodies. The root cause of this punishment is that when one unnecessarily accumulates wealth, one becomes more and more degraded, not knowing that his wealth will be finished with his next birth.
