sa baddha-hrdayas tasminn
mumude jaratho bhrsam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because of the child’s broken language and awkward movements, old Ajamila was very much attached to him. He always took care of the child and enjoyed the child’s activities.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Here it is clearly mentioned that the child Narayana was so young that he could not even speak or walk properly. Since the old man was very attached to the child, he enjoyed the child’s activities, and because the child’s name was Narayana, the old man always chanted the holy name of Narayana. Although he was referring to the small child and not to the original Narayana, the name of Narayana is so powerful that even by chanting his son’s name he was becoming purified (harer nama harer nama harer namaiva kevalam). Srila Rupa Gosvami has therefore declared that if one’s mind is somehow or other attracted by the holy name of Krsna (tasmat kenapy upayena manah krsne nivesayet), one is on the path of liberation. It is customary in Hindu society for parents to give their children names like Krsnadasa, Govinda dasa, Narayana dasa and Vrndavana dasa. Thus they chant the names Krsna, Govinda, Narayana and Vrndavana and get the chance to be purified.
