• dvaipāyanaḥ — Vedavyāsa
  From dvīpa (island) — born on an island in the Yamunā. The compiler of the four Vedas, the Mahābhārata, the Purāṇas, and the Bhāgavatam itself. His physical presence at this sacrifice is the Bhāgavatam's own author standing inside the scene he will later write.
• vasiṣṭhaḥ — the sage Vasiṣṭha
  Family priest of the Ikṣvāku line — Rāma's guru. His name in the list links the Rājasūya backward to the Rāmāyaṇa lineage, signaling that the same dharma-stream now waters the Pāṇḍava field.
• viśvāmitraḥ — the sage Viśvāmitra
  The kṣatriya who became a brahmarṣi by tapas. Gāyatrī's seer. His name beside Vasiṣṭha's records the most famous reconciled rivalry of the śāstras — both honor Kṛṣṇa together at this yajña.
• rāmaḥ bhārgavaḥ — Pāraśurāma of the Bhṛgus
  The Lord's previous āveśa-avatāra is present at His pūrṇa-avatāra's sacrifice. Gauḍīyas read the line as Bhagavān's own former form taking a seat as ṛtvik for His later, fuller form — a quiet image of avatāra-tāratamya.

Picture a wedding where every uncle on every side of the family has come — no branch missing. The Rājasūya draws the full roster of ṛṣis (Vyāsa, Vasiṣṭha, Viśvāmitra, Paraśurāma, Parāśara, Vaiśampāyana…) so that no Vedic lineage can later say 'we were not represented when Kṛṣṇa was honored first.'
