Srimad Bhagavatam Canto 06, Chapter 01, Text 30

SB 6.1.30

nisamya mriyamanasya
 mukhato hari-kirtanam
bhartur nama maharaja
 parsadah sahasapatan
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear King, the order carriers of Visnu, the Visnudutas, immediately arrived when they heard the holy name of their master from the mouth of the dying Ajamila, who had certainly chanted without offense because he had chanted in complete anxiety.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Srila Visvanatha Cakravarti Thakura remarks, hari-kirtanam nisamyapatan, katham-bhutasya bhartur nama bruvatah: the order carriers of Lord Visnu came because Ajamila had chanted the holy name of Narayana. They did not consider why he was chanting. While chanting the name of Narayana, Ajamila was actually thinking of his son, but simply because they heard Ajamila chanting the Lord’s name, the order carriers of Lord Visnu, the Visnudutas, immediately came for Ajamila’s protection. Hari-kirtana is actually meant to glorify the holy name, form, pastimes and qualities of the Lord. Ajamila, however, did not glorify the form, qualities or paraphernalia of the Lord; he simply chanted the holy name. Nevertheless, that chanting was sufficient to cleanse him of all sinful activities. As soon as the Visnudutas heard their master’s name being chanted, they immediately came. In this regard Srila Vijayadhvaja Tirtha remarks: anena putra-sneham antarena pracinadrsta-balad udbhutaya bhaktya bhagavan-nama-sankirtanam krtam iti jñayate. “Ajamila chanted the name of Narayana because of his excessive attachment to his son. Nevertheless, because of his past good fortune in having rendered devotional service to Narayana, he apparently chanted the holy name in full devotional service and without offenses.”
