nīca-jāti nahe kṛṣṇa-bhajane ayogya
sat-kula-vipra nahe bhajanera yogya
nīca-jāti—a lowborn person; nahe—is not; kṛṣṇa-bhajane—in discharging devotional service; ayogya—unfit; sat-kula-vipra—a brāhmaṇa born in a very respectable aristocratic family; nahe—is not; bhajanera yogya—fit for discharging devotional service.
"A person born in a low family is not unfit for discharging devotional service to Lord Kṛṣṇa, nor is one fit for devotional service simply because he is born in an aristocratic family of brāhmaṇas.
