SB 1.12.16, Translation and Purport: The brāhmaṇas said: This spotless son has been restored by the all-powerful and all-pervasive Lord Viṣṇu, the Personality of Godhead, in order to oblige you. He was saved when he was doomed to be destroyed by an irresistible supernatural weapon. The child Parīkṣit was saved by the all-powerful and all-pervasive Viṣṇu (Lord Kṛṣṇa) for two reasons. The first reason is that the child in the womb of his mother was spotless due to his being a pure devotee of the Lord. The second reason is that the child was the only surviving male descendant of Puru, the pious forefather of the virtuous King Yudhiṣṭhira. The Lord wants to continue the line of pious kings to rule over the earth as His representatives for the actual progress of a peaceful and prosperous life. After the Battle of Kurukṣetra, even up to the next generation of Mahārāja Yudhiṣṭhira was annihilated, and there were none who could generate another son in the great royal family. Mahārāja Parīkṣit, the son of Abhimanyu, was the only surviving heir apparent in the family, and by the irresistible supernatural brahmāstra weapon of Aśvatthāmā, he was forced to be annihilated. Lord Kṛṣṇa is described herein as Viṣṇu, and this is also significant. Lord Kṛṣṇa, the original Personality of Godhead, does the work of protection and annihilation in His capacity of Viṣṇu. Lord Viṣṇu is the plenary expansion of Lord Kṛṣṇa. The all-pervasive activities of the Lord are executed by Him in His Viṣṇu feature.
