dvijah pasad vinirmukto
gata-bhih prakrtim gatah
vavande sirasa visnoh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Having been released from the nooses of Yamaraja’s servants, the brahmana Ajamila, now free from fear, came to his senses and immediately offered obeisances to the Visnudutas by bowing his head at their lotus feet. He was extremely pleased by their presence, for he had seen them save his life from the hands of the servants of Yamaraja.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vaisnavas are also Visnudutas because they carry out the orders of Krsna. Lord Krsna 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 Vaisnava therefore tries to bring conditioned souls to their senses. Those who are fortunate like Ajamila are saved by the Visnudutas, or Vaisnavas, and thus they return back home, back to Godhead.
