So the contradiction was answered by Śukadeva Gosvāmī not personally; he took authority. What is that authority? He said immediately, "My dear King, this answer I shall not give you, but a similar answer was put forward by your grandfather, Mahārāja Yudhiṣṭhira, to your other grandfather, Kṛṣṇa."
Kṛṣṇa also happened to be grandfather of Mahārāja Parīkṣit. Because Kṛṣṇa's sister was married to Arjuna, and Mahārāja Parīkṣit is the grandson of Subhadrā, Arjuna's wife. Therefore Kṛṣṇa also happens to be grandfather of Mahārāja Parīkṣit, and Mahārāja Yudhiṣṭhira also happens to be grandfather, being the eldest brother of his grandfather.
So Kṛṣṇa is the authority. Therefore Śukadeva Gosvāmī is giving authoritative answer as it was spoken by Kṛṣṇa. This is the way of speaking. One should cite authority. Śukadeva Gosvāmī was not less authority. As I described the other day that there are twelve authorities.
