O king of daityas, since childishness is the root of all these evils, it behoveth thee to renounce thy ire against this boy. If he according to our instructions, does not abandon the cause of Hari we shall then concert infallible measures to bring about his destruction". Parāçara said Thereupon being thus solicited by the priests the king of Daityas had his son brought out from the flames by the Daityas.
In plain words: The priests say the boy's behavior comes from being young and ask the king to let go of his anger. If Prahlada still will not give up worshipping Hari (Vishnu), they will find a sure way to kill him. The king agrees and has his son pulled out of the fire.
