The attraction for material enjoyment is due to an increase of the mode of passion. A person in the material world, when favored by the material opulence of riches, generally becomes addicted to three things — intoxication, sex and gambling. Materially opulent men, being puffed up with the accumulation of wealth, also become so merciless that they indulge in killing animals by opening slaughterhouses. And they think that they themselves will never die. Such foolish persons, forgetting the laws of nature, become overly infatuated with the body.
