SB 6.3.29
jihva na vakti bhagavad-guna-namadheyam
cetas ca na smarati tac-caranaravindam
krsnaya no namati yac-chira ekadapi
tan anayadhvam asato ’krta-visnu-krtyan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear servants, please bring to me only those sinful persons who do not use their tongues to chant the holy name and qualities of Krsna, whose hearts do not remember the lotus feet of Krsna even once, and whose heads do not bow down even once before Lord Krsna. Send me those who do not perform their duties toward Visnu, which are the only duties in human life. Please bring me all such fools and rascals.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word visnu-krtyan is very important in this verse because the purpose of human life is to please Lord Visnu. Varnasrama-dharma is also meant for that purpose. As stated in the Visnu Purana (3.8.9):
varnasramacaravata
purusena parah puman
visnur aradhyate pantha
nanyat tat-tosa-karanam
Human society is meant to follow strictly the varnasrama-dharma, which divides society into four social divisions (brahmana, ksatriya, vaisya and sudra) and four spiritual divisions (brahmacarya, grhastha, vanaprastha and sannyasa). Varnasrama-dharma easily brings one nearer to Lord Visnu, who is the only true objective in human society. Na te viduh svartha-gatim hi visnum: unfortunately, however, people do not know that their self-interest is to return home, back to Godhead, or to approach Lord Visnu. Durasaya ye bahir-artha-maninah: instead, they are simply bewildered. Every human being is expected to perform duties meant for approaching Lord Visnu. Therefore Yamaraja advises the Yamadutas to bring him those persons who have forgotten their duties toward Visnu (akrta-visnu-krtyan). One who does not chant the holy name of Visnu (Krsna), who does not bow down to the Deity of Visnu, and who does not remember the lotus feet of Visnu is punishable by Yamaraja. In summary, all avaisnavas, persons unconcerned with Lord Visnu, are punishable by Yamaraja.
