The word viṣṇu-kṛtyān is very important in this verse because the purpose of human life is to please Lord Viṣṇu. Varṇāśrama-dharma is also meant for that purpose. As stated in the Viṣṇu Purāṇa (3.8.9):
- puruṣeṇa paraḥ pumān
- viṣṇur ārādhyate panthā
- nānyat tat-toṣa-kāraṇam
- (CC Madhya 8.58)
Human society is meant to follow strictly the varṇāśrama-dharma, which divides society into four social divisions (brāhmaṇa, kṣatriya, vaiśya and śūdra) and four spiritual divisions (brahmacarya, gṛhastha, vānaprastha and sannyāsa). Varṇāśrama-dharma easily brings one nearer to Lord Viṣṇu, who is the only true objective in human society. Na te viduḥ svārtha-gatiṁ hi viṣṇum: (SB 7.5.31) unfortunately, however, people do not know that their self-interest is to return home, back to Godhead, or to approach Lord Viṣṇu. Durāśayā ye bahir-artha-māninaḥ: instead, they are simply bewildered. Every human being is expected to perform duties meant for approaching Lord Viṣṇu. Therefore Yamarāja advises the Yamadūtas to bring him those persons who have forgotten their duties toward Viṣṇu (akṛta-viṣṇu-kṛtyān). One who does not chant the holy name of Viṣṇu (Kṛṣṇa), who does not bow down to the Deity of Viṣṇu, and who does not remember the lotus feet of Viṣṇu is punishable by Yamarāja. In summary, all avaiṣṇavas, persons unconcerned with Lord Viṣṇu, are punishable by Yamarāja.
