He selected Kṛṣṇa-dvaipāyana (Vyāsa), Bharadvāja, Sumantu, Gotama and Asita, along with Vasiṣṭha, Cyavana, Kaṇva, Maitreya, Kavaṣa and Trita. He also chose Viśvāmitra, Vāmadeva, Sumati, Jaimini, Kratu, Paila and Parāśara, as well as Garga, Vaiśampāyana, Atharvā, Kaśyapa, Dhaumya, Rāma of the Bhārgavas, Āsuri, Vītihotra, Madhucchandā, Vīrasena and Akṛtavraṇa, appointing them as ṛtvij priests for the sacrifice.
King Yudhiṣṭhira invited all these exalted brāhmaṇas to act in different capacities as priests, advisers and so on.
This verse names prominent ṛṣis—such as Vyāsa, Bharadvāja, Vasiṣṭha, Kaṇva and Maitreya—who attended the Rājasūya, showing the sacrifice was honored by the highest Vedic authorities.
He is describing the grandeur and legitimacy of the Rājasūya: the presence of renowned sages indicates that the assembly and the sacrificial proceedings were conducted according to dharma and witnessed by saintly authorities.
Seek saintly guidance and keep spiritually serious company—important decisions and worship become purified and steady when supported by sādhus and scriptural authority.
