Parîkṣit, the conqueror of enemies’ towns, was the son of Abhimanyu, and he became the father of Janamejaya, the Pious. When Janamejaya favored Ṛiṣi Yâjñavalkya, whom he appointed as his Brahmâ priest at the Sacrifice, then the sage Vaiśampâyana cursed him to the effect : “The innovations introduced by you O man of perverted intelligence, will not be respected. They will be honored only so long as thou wilt remain on earth.”—57-59.
