Srimad Bhagavatam Canto 06, Chapter 02, Text 42

SB 6.2.42

yarhy uparata-dhis tasminn
 adraksit purusan purah
upalabhyopalabdhan prag
 vavande sirasa dvijah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When his intelligence and mind were fixed upon the form of the Lord, the brahmana Ajamila once again saw before him four celestial persons. He could understand that they were those he had seen previously, and thus he offered them his obeisances by bowing down before them.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The Visnudutas who had rescued Ajamila came before him again when his mind was firmly fixed upon the form of the Lord. The Visnudutas had gone away for some time to give Ajamila a chance to become firmly fixed in meditation upon the Lord. Now that his devotion had matured, they returned to take him. Understanding that the same Visnudutas had returned, Ajamila offered them his obeisances by bowing down before them.
