King Yudhiṣṭhira was known as ajātaśatru, or a person who has no enemy. Therefore, when all men, all demigods, all kings, sages and saints saw the successful termination of the Rājasūya yajña performed by King Yudhiṣṭhira, they became very happy. That Duryodhana alone was not happy was astonishing to Mahārāja Parīkṣit, and therefore he requested Śukadeva Gosvāmī to explain this.
