• pūrṇasya — of the perfectly complete one
  Pūrṇa — full, complete. The same word used in the Īśa Upaniṣad's pūrṇam adaḥ pūrṇam idam. Bhagavān is pūrṇa, and yet His devotee gives Him gifts. Gauḍīya doctrine: dāna to the pūrṇa is the only dāna whose value is not in the gift but in the giving.
• bhaktitaḥ — out of devotion
  Bhakti + ablative suffix -taḥ — 'from devotion'. The motive of the entire gift is named explicitly: not dharma, not custom, not display. Bhakti. Gauḍīya kīrti-bhakti is the same root in act: action poured outward from the bhāva that gives.
• dāsībhiḥ — with maidservants
  Dāsī — the same word the queens have applied to themselves (verses 10, 14, 39). The bride brings dāsīs to serve, but she calls herself a dāsī too. The chapter quietly collapses queen and maidservant into a single bhakti-category.
• mahā - arhāṇi — extremely valuable
  Mahā (great) + arha (worthy). The qualifier applied to the āyudhas Bṛhatsena gives. Bṛhatsena's gifts to Bhagavān, who is Himself the bearer of every weapon, must be mahā-arha to be worth offering at all. The act is pure relationship — Kṛṣṇa has no need, the father has every need to give.
• bhaṭa - ibha - ratha - vājibhiḥ — with foot soldiers, elephants, chariots, and horses
  Compound of the four traditional aṅgas of the army. Bṛhatsena gives a complete caturaṅginī as part of the dowry — the same word appeared at verse 13-14 in Nagnajit's gift to Kṛṣṇa with Satyā. The pattern of royal dāna repeats.

• Where do I give the Lord small gifts because I think He needs little?
• What would extravagant offering look like, motivated by love?

Now Bṛhatsena turns toward Kṛṣṇa Himself — the only recipient he calls pūrṇa, the perfectly complete. The dowry includes maidservants ornamented, infantry-elephant-chariot-horse divisions, and mahā-arha weapons. To give to Bhagavān is the strangest possible act — He lacks nothing — yet bhakti gives anyway, because the giving itself is the relationship.
