SB 5.5.4
nunam pramattah kurute vikarma
yad indriya-pritaya aprnoti
na sadhu manye yata atmano ’yam
asann api klesada asa dehah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Begging, borrowing and stealing to live for sense gratification is condemned in this verse because such consciousness leads one to a dark, hellish condition. The four sinful activities are illicit sex, meat-eating, intoxication and gambling. These are the means by which one gets another material body that is full of miseries. In the Vedas it is said: asango hy ayam purusah. The living entity is not really connected with this material world, but due to his tendency to enjoy the material senses he is put into the material condition. One should perfect his life by associating with devotees. He should not become further implicated in the material body.
