SB 4.29.41
etair upadruto nityam
jiva-lokah svabhavajaih
na karoti harer nunam
kathamrta-nidhau ratim
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because the conditioned soul is always disturbed by the bodily necessities such as hunger and thirst, he has very little time to cultivate attachment to hearing the nectarean words of the Supreme Personality of Godhead.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Unless one is associated with devotees, he cannot cultivate Krsna consciousness. Nirjana-bhajana, cultivating Krsna consciousness in a solitary place, is not possible for the neophyte, for he will be disturbed by the bodily necessities — eating, sleeping, mating and defending. Being so disturbed, one cannot cultivate Krsna consciousness. We therefore see that devotees known as sahajiya, who make everything very easy, do not associate with advanced devotees. Such persons, in the name of devotional activities, are addicted to all kinds of sinful acts — illicit sex, intoxication, gambling and meat-eating. There are many so-called devotees passing themselves off as devotees while engaging in these sinful activities. In other words, one who is influenced by sinful activity cannot be accepted as a person in Krsna consciousness. A person addicted to sinful life cannot develop Krsna consciousness, as indicated in this verse.
