• antaḥ - pura — of the royal palace
  Compound: antar (inner) + pura (city). The inner apartments of the palace — household members, queens' attendants. Gauḍīyas note: the witnesses are not strangers; they are Kṛṣṇa's intimate household, and even they are surprised.
• amala — spotless
  Adjective: stainless, pure. Kṛṣṇa's kīrti is amala because nothing about His honoring of the brāhmaṇa contradicts His glory — quite the opposite. Gauḍīyas note: bhakta-vatsalya is the glory, not a derogation of it.
• vismitaḥ — amazed
  Past participle of vi-√smi. Vismaya — the rasa of wonder. Gauḍīyas note: vismaya is the door rasa into adbhuta-rasa, and from there into the recognition that Kṛṣṇa's mādhurya exceeds all categories.
• avadhūtam — the unkempt brāhmaṇa
  Past participle of ava-√dhū — 'shaken off.' Avadhūta in śāstra is one who has shaken off all worldly distinctions. The palace sees only his outer ku-caila; the Lord sees his interior avadhūtatva.
• sabhājitam — honored
  Past participle of saṁ-√bhāj. Sabhājana — honored, welcomed. The same root as bhakti; here the Lord bhajatis His friend — the verb of bhakti turns inside-out, with Bhagavān as the worshiper.

• Where does my own honoring follow social calculus rather than bhakti's logic?
• What public expression of honor would scandalize my circle in a good way?

Watching a crown change heads in a marketplace: the palace residents see a ragged man being treated as a deity, and their established categories crack. The verse is a snapshot of vismaya — wonder — that opens space for the truth they are about to articulate.
