In plain words
What was his Bhakti and surrender like?
Drinking water, eating food, sleeping, walking, talking, playing, singing, he was always in the thought of Hari alone. Seeing his son travel on this noble path, the father was vexed. With the thought that if this boy were left this way he might simply go mad, he sent for good, strict teachers, Caṇḍa and Amarka; their very names are those of Caṇḍālas. Caṇḍa and Amarka means those who do not change. He sent for such men and handed Prahlāda over to them. They were men who had taken refuge with Hiraṇyakaśipu for their livelihood, not for the supreme goal of life. What did they teach? God means Hiraṇyakaśipu himself. Divine power means that Hiraṇyakaśipu's power alone is divine power. If you ask who is all-knowing, it is Hiraṇyakaśipu. If you ask who is everywhere, it is Hiraṇyakaśipu. Urged on in this way by Hiraṇyakaśipu, to please him, these teachers went on giving teachings of this kind. But for the little boy, Hiraṇyakaśipu called the teacher: “You must teach my son only these three, Dharma, artha and kāma. You must teach him the whole conduct of married life through artha and kāma alone, and change this boy's heart,” he said. Caṇḍa and Amarka set about giving such contrary teachings. Taking the time when those teachers were away, Prahlāda would gather the boys of his own age and, instead of going off to play, teach them the thought of Hari, which is eternal Satya.
He would teach the children. “Our teachers are not giving us the right learning. Through the desires of the world and its pleasures they are drawing us still further into these. Beasts, birds and wild animals too go into the enjoyment of the things of the world. Jantūnāṃ narajanma durlabham. What is special in this? Born a human being, to scramble after these pleasures like beasts, birds and wild animals is not right Dharma. Our whole life must be offered to Hari. There is no fruit greater than that.” In this way Prahlāda went on teaching. “Children! We are only human beings. We are the heirs of Mādhava. What effort are we making for this inheritance? Our wealth and riches, all of them, are not artha and kāma. Bhakti is our chief goal. Dharma is our chief way of walking. Prema is the breadth of our heart. We human beings are those bound by the principle of these three. So our duty is to purify thought, word and deed and to see the Trimūrti within that threefold purity.”
