In plain words
The secrets of Divinity are very subtle
Virocana, the son of Prahlāda, and Sudhīra, the son of Aṅgīrasa, made a wager between them. Whoever lost the wager was to give his life to the one who won. Prahlāda was the judge between the two. He was Dharma embodied. He judged that Virocana had lost the debate and that Sudhīra, the son of Aṅgīrasa, had won. Then Virocana took a sword and made ready to strike off his own head. Because he did as he had said, Sudhīra's heart melted at once. ‘Today your father has judged justly, by Satya, righteously. If I take your life, his son's, I shall be the one who brought your father pain. I do not wish to cause pain to such a just judge. So I do not want your life,’ he said, and handed the son back to his father.
In the same way Paraśurāma's father gave him a harsh command and ordered him to carry it out. What was it? Some time before, when Jamadagni's wife went to the river to fetch water, she saw a man. She was pure of heart. But out of curiosity she looked, wondering, ‘Who is that going by?’ Seeing him: ‘Ah! How handsome he is!’ she thought. When she came home, Jamadagni looked at her, grasped by his divine sight what had happened, and, because her mind had wavered, called Paraśurāma and commanded him to hew off his mother's head (to sever it). Paraśurāma did not flinch in the least at that moment. Obeying his father's command, he cut his mother's throat. Then his father, pleased: “Paraśurāma! Ask for whatever you want,” he said. “Father! Bring my mother back to life,” he said. Here, because he obeyed his father's command, Paraśurāma's wish was fulfilled. If instead you say, ‘Fulfil my wish,’ without obeying, how will it be fulfilled?
So subtle are the secrets of Divinity. In the principle of Kṛṣṇa too there are many things with such inner meanings. But people, going by their own feelings, multiply many false senses, invent all sorts of meanings, believe them, forget the truth, and bring harm upon themselves.
