• visphurantīm — appearing effulgent
  Present participle of vi + √sphur (to shine forth, throb). She is throbbing-bright — not lit from outside but glowing from within. The bhāva radiates as light. Gauḍīya: the bhakta's body undergoes visible change when Bhagavān's blessing rests on it.
• devīm vaimānikīm iva — as if a demigoddess come in a heavenly airplane
  devī (goddess) + vaimānikī (one who travels by vimāna) + iva. The wife has not actually flown anywhere — she has stayed home — yet she looks like a sky-goddess. The poet inverts cosmic geography: the celestial has descended into the house.
• niṣka-kaṇṭhīnām — (maidservants) with lockets on their necks
  Compound: niṣka (a gold ornament, locket) + kaṇṭha (neck). Even the maidservants wear gold. The chapter's wealth pours through the household at every level — not concentrated on the master but distributed.
• vismitaḥ — amazed
  Past participle of vi + √smi (to wonder). The same vismaya-bhāva from verse 15 returns. Sudāmā's whole homecoming is a sustained vismaya — and the poet keeps marking it, because vismaya is the rasa-component the verse wants the reader to share.

A pauper husband stands in the doorway and sees his wife — the same woman who had been thin from fasting — now standing in the middle of jeweled maidservants, shining as if she had stepped out of a vimāna. Kṛṣṇa's gift has rewritten the household's geography, and the doorway is the boundary between two lives.
