Who · King Nābhi, Merudevī, Lord Viṣṇu, Lord Ṛṣabhadeva, the priests
The story · King Nābhi and his wife Merudevī worshiped Lord Viṣṇu through sacrifices, desiring a son. Pleased with their worship, the Lord appeared before them in His four-handed form, and the priests prayed for a son like Him. Because no one is equal to the Supreme Person, He agreed to appear Himself as Ṛṣabhadeva. Nābhi raised Him with great affection, and Ṛṣabhadeva displayed incomparable qualities and signs of the Supreme Lord. Nābhi later entrusted the kingdom to Him and retired to Badarikāśrama to worship Vāsudeva.
What it teaches · The Supreme Personality of Godhead is without an equal and is merciful to His devotees. The priests approached Him as eternal servants, asking Him to accept their service.
