gata-bhīḥ prakṛtiṁ gataḥ
vavande śirasā viṣṇoḥ
Vaiṣṇavas are also Viṣṇudūtas because they carry out the orders of Kṛṣṇa. Lord Kṛṣṇa is very eager for all the conditioned souls rotting in this material world to surrender to Him and be saved from material pangs in this life and punishment in hellish conditions after death. A Vaiṣṇava therefore tries to bring conditioned souls to their senses. Those who are fortunate like Ajāmila are saved by the Viṣṇudūtas, or Vaiṣṇavas, and thus they return back home, back to Godhead.
