uvāca tān smayamānaḥ
When he was in the womb of his mother, Prahlāda Mahārāja listened to the words of Nārada Muni. One cannot imagine how the baby in embryo could hear Nārada, but this is spiritual life; progress in spiritual life cannot be obstructed by any material condition. This is called ahaituky apratihatā. Reception of spiritual knowledge is never checked by any material condition. Thus Prahlāda Mahārāja, from his very childhood, spoke spiritual knowledge to his class friends, and certainly it was effective, although all of them were children.
