• dakṣiṇāḥ — gifts in remuneration
  Dakṣiṇā — the proper completion of any ritual; without it the rite is incomplete (cf. SB 1.8). Vasudeva honors śāstric procedure to its end.
• gāvaḥ — cows
  Cow-dāna is the highest dakṣiṇā. In Gauḍīya theology cows are the wealth-form Kṛṣṇa Himself most loves (cf. Govinda, Gopāla). The gift is rasa-resonant.
• rukma - mālāḥ — with gold necklaces
  The cows themselves wear gold — already worshiped before being given. The dāna's recipient (brāhmaṇa) and the gift (cow) are both pre-honored. Maximum decorum.
• sa - vatsāḥ — with their calves
  Sa-vatsā = with calf. Cow-with-calf dāna is the higher form; the mother-bond is not severed. Vātsalya in the gift itself.
• kṣauma - mālinīḥ — wearing linen garlands
  Kṣauma = linen, fine cloth; mālinī = garlanded. The cows wear kṣauma garlands — the bovine equivalent of brāhmaṇa attire. The whole tableau is liturgical.

Vasudeva's gift of gold-garlanded cows with calves, in linen wreaths, to the well-adorned brāhmaṇas is the householder's full breath out after years of held terror. The opulence is not display — it is the unsealing of a vow Kaṁsa had kept locked.
