• kṛṣṇa-devatāḥ — whose worshipable Deity is Kṛṣṇa
  kṛṣṇa + devatā (worshipable). The Vṛṣṇis are kṛṣṇaika-devatā. Gauḍīyas read this as the verse's quiet declaration: the entire Yadu clan is, on the Bhāgavata's reckoning, a worshipping community whose iṣṭa-devatā is Kṛṣṇa Himself.
• prāvṛṣam — the rainy season
  From √vṛṣ (to rain). The monsoon. Gauḍīyas note the seasonal register: the chapter began at the eclipse and ends with the monsoon's approach. Time has moved; the cosmic event that gathered everyone is over.
• dvāravatīm — to Dvārakā
  From dvāra (gate). The city with many gates. Gauḍīyas treat Dvārakā as Kṛṣṇa's prabhava-pīṭha in the aiśvarya-register — the queenly capital that complements Vraja's mādhurya.
• pratiyāteṣu — having departed
  Locative plural of prati + yāta (gone back). Used in the locative-absolute construction with bandhuṣu (relatives). Gauḍīyas note the verse's grammar: only after relatives have departed do the Vṛṣṇis turn home — the departure is not abandonment but completion.

• What spiritual high am I trying to extend beyond its appointed time?
• How do I carry the festival back into the rainy season's daily work?

With Vraja gone and the monsoon coming, the Vṛṣṇis turn back to Dvārakā — kṛṣṇa-devatāḥ, those whose Deity is Kṛṣṇa. The phrase quietly does the chapter's work in two compound members: the Yadus are not just royals returning home, they are Kṛṣṇa-worshipers traveling with their Deity in the chariot.
