PURPORT

The four miserable conditions are due to the four kinds of sinful activities, known as (1) pataka, (2) urupataka, (3) maha-pataka and (4) atipataka-preliminary sin, very great sin, greater sin and topmost sin. However, Krsna assures the devotee, aham tvam sarva-papebhyo moksayisyami ma sucah: "I will protect you from all sinful reactions. Do not fear." The word sarva-papebhyah indicates four kinds of sinful activity. As soon as the devotee surrenders unto Krsna's lotus feet, he is certainly relieved from all sinful activities and their results. The four basic sinful activities are summarized as illicit sex, intoxication, gambling and meat-eating.
