When a sinful man enjoys material facilities, foolish people sometimes think, "How is it that this sinful man is enjoying whereas a pious man is suffering?" By the will of the Supreme, a sinful man is sometimes given the chance to enjoy the material world as if he were not under the clutches of material nature, just so that he may be fooled. A sinful man who acts against the laws of nature must be punished, but sometimes he is given a chance to play and enjoy this material world.
Indeed it is very difficult to understand this material world.
