• ādyam-puruṣam — the original Supreme Person
  Phrase: ādya (first, original) + puruṣa (person). Sūta uses one of the Bhāgavata's high titles for Kṛṣṇa at the moment the brāhmaṇa first sees Him — the verse classes the meeting as a darśana of the Ādi-puruṣa, not merely an audience with Dvārakā's king.
• pratīhāraiḥ-praveśitaḥ — brought inside by the gatekeepers
  Compound + participle. The dvāra-pālas of Dvārakā are themselves residents of Vaikuṇṭha-rank; their function as gatekeepers is structurally the same as Jaya-Vijaya. The brāhmaṇa is conducted in by qualified servants — Vaiṣṇava etiquette mirrored into the architecture.
• kāñcana-āsane — on a golden throne
  Compound: kāñcana (gold) + āsana (seat). The verse's aiśvarya-register is foregrounded — Kṛṣṇa receives the brāhmaṇa from a throne of gold. Gauḍīyas read this as the doctrinally correct context for Rukmiṇī's letter, which speaks Bhagavān's full majesty as well as His beauty.

The brāhmaṇa walks into Dvārakā and walks straight into the golden throne-room — like a man bringing a folded note to a king, only the king turns out to be the Original Person seated as if waiting for that very note. Gatekeepers, throne, gold — every Vedic mark of majesty is in place precisely so that the messenger can recognize whom he has reached.
