सुदुस्तरं समुत्तीर्य कृष्णेनासीद् गतज्वर: ॥ ३० ॥
ittham — in this manner; rājā — the King; dharma — of the lord of religion (Yamarāja); sutaḥ — the son; manaḥ-ratha — of his desires; mahā — huge; arṇavam — the ocean; su — very; dustaram — difficult to cross; samuttīrya — successfully crossing; kṛṣṇena — through the agency of Lord Kṛṣṇa; āsīt — he became; gata-jvaraḥ — freed of his feverish condition.
Thus King Yudhiṣṭhira, the son of Dharma, was at last relieved of his burning ambition, having by the grace of Lord Kṛṣṇa successfully crossed the vast and formidable ocean of his desires.
The previous chapters of Śrīmad-Bhāgavatam clearly explain that King Yudhiṣṭhira intensely desired to demonstrate to the world the supremacy of Kṛṣṇa, the Supreme Personality of Godhead, and the blessings received by those who surrender to Him. To do this, King Yudhiṣṭhira performed the Rājasūya sacrifice, a very difficult task.
Śrīla Prabhupāda writes in this connection: “In the material world, everyone has a particular type of desire to be fulfilled, but one is never able to fulfill his desires to his full satisfaction. But King Yudhiṣṭhira, because of his unflinching devotion to Kṛṣṇa, could fulfill all his desires successfully by the performance of the Rājasūya sacrifice. From the description of the Rājasūya yajña, it appears that such a function is a great ocean of opulent desires. It is not possible for an ordinary man to cross over such an ocean; nevertheless, by the grace of Lord Kṛṣṇa, King Yudhiṣṭhira was able to cross over it very easily, and thus he became freed from all anxieties.”
