SB 6.1.25, Translation and Purport

Because of the child's broken language and awkward movements, old Ajāmila was very much attached to him. He always took care of the child and enjoyed the child's activities.

Here it is clearly mentioned that the child Nārāyaṇa 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 Nārāyaṇa, the old man always chanted the holy name of Nārāyaṇa. Although he was referring to the small child and not to the original Nārāyaṇa, the name of Nārāyaṇa is so powerful that even by chanting his son's name he was becoming purified (harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21)). Śrīla Rūpa Gosvāmī has therefore declared that if one's mind is somehow or other attracted by the holy name of Kṛṣṇa (tasmāt kenāpy upāyena manaḥ kṛṣṇe niveśayet (SB 7.1.32)), one is on the path of liberation. It is customary in Hindu society for parents to give their children names like Kṛṣṇadāsa, Govinda dāsa, Nārāyaṇa dāsa and Vṛndāvana dāsa.
