• nanda - vrajam — the pastures of Nanda
  Compound: Nanda + Vraja. Reinforces verse 7's framing — the dhāma is identified through Nanda, not through Kṛṣṇa's residency. Gauḍīyas read this as a quiet doctrinal point: Vraja's owner is its eternal owner, regardless of līlā-movement.
• śrīmān — the fortunate one
  Possessing śrī. Uddhava is called śrīmān at the very moment of his Vraja-arrival because contact with the dhāma is itself the conferring of śrī. Gauḍīya tīkā: it is not Uddhava's prior śrī that earns him Vraja, but Vraja that bestows śrī on him.
• channa - yānaḥ — whose passage was concealed
  Compound: channa (hidden) + yāna (going). The chariot enters unseen — a striking detail, because Vraja-residents will not know Uddhava is there until morning (verse 47). The Bhāgavatam stages the messenger's entry as a kind of pradoṣa-mystery.
• khura - reṇubhiḥ — by the dust of (the cows') hooves
  Compound: khura (hoof) + reṇu (dust). The very substance Brahmā prayed for in 10.14.34. Uddhava is sanctified by go-pada-rajas before he sets foot on the ground.
• nimlocati — while (the sun) was setting
  Locative absolute. Sunset is the cows' return-time (godhūli) — the most charged hour of the cowherd day. Gauḍīya kāvya elevates godhūli-līlā as a discrete topos; the Bhāgavatam locates Uddhava's arrival inside it.
• vibhāvasau — the sun
  Locative of vibhāvasu — literally 'one whose wealth is light.' A theologically loaded sun-word: the wealth (vasu) of light withdraws as Uddhava arrives. The next morning's bhagavati udite sūrye in verse 47 will mark the answering daybreak.

• Where might Kṛṣṇa's messenger be arriving in your life right now, hidden by ordinary dust?
• Could you watch the unremarkable evening for divine arrivals?

The Lord arranges that Uddhava arrive cloaked in the dust kicked up by the homeward cows — the same dust that, in the Tenth Canto's own theology, the gods envy on Kṛṣṇa's lotus feet. Uddhava enters Vraja anointed by go-rajas before he ever meets a single resident.
