• brahma - kṣatra - sabhā — the assembly of brāhmaṇas and kṣatriyas
  Compound: brahma (brāhmaṇa) + kṣatra (kṣatriya) + sabhā (assembly). The two upper varṇas seated together. Gauḍīyas: the verse pictures the kingdom's full upper structure ratifying Yudhiṣṭhira — and through him, Kṛṣṇa's agra-pūjā.
• śuśubhe — he appeared brilliant
  Perfect of √śubh (to shine, to be auspicious). Cognate of śubha. The same root that names auspiciousness names his post-yajña glow.
• sura - rāṭ iva — like the King of the demigods
  Compound + particle: sura + rāj (Indra) + iva (as). Yudhiṣṭhira's earthly status now mirrors Indra's heavenly one. The Bhāgavatam allows the comparison briefly — but only because the Pāṇḍava's first-honor went to a Lord above Indra.
• avabhṛthyena snātaḥ — bathed by the avabhṛtha
  Instrumental + participle: avabhṛthya (the avabhṛtha ritual) + snāta (bathed). The bath that completes a great Vedic sacrifice. Gauḍīyas: snāna in the Bhāgavata is always two-layered — the outer water and the inner bhāva.

After every great work, the worker bathes — and the bath becomes the worker's coronation. Yudhiṣṭhira, fresh from avabhṛtha, sits among brāhmaṇas and kṣatriyas like Indra among the devas. The Rājasūya's interior has rearranged him.
