When a person considers sense gratification the aim of life, he certainly becomes mad after materialistic living and engages in all kinds of sinful activity. He does not know that due to his past misdeeds he has already received a body which, although temporary, is the cause of his misery. Actually the living entity should not have taken on a material body, but he has been awarded the material body for sense gratification. Therefore I think it not befitting an intelligent man to involve himself again in the activities of sense gratification by which he perpetually gets material bodies one after another.
