• nāga-ayuta-bala-anvitaḥ — endowed with the strength of ten thousand elephants
  Compound: nāga (elephant) + ayuta (ten thousand) + bala (strength) + anvita (endowed). Sanskrit's heroic measure. Aniruddha — etymologically 'unobstructable' — possesses ten thousand elephants' force. The name and the capacity match.
• mahā-rathaḥ — the great chariot-warrior
  Compound: mahā + ratha. Pradyumna inherits this rank and his son Aniruddha exceeds it. Gauḍīya pattern: descent of svarūpa-śakti through Vaiṣṇava lineage is not metaphor — it is genealogical.
• rukmiṇaḥ — of Rukmī
  Genitive of Rukmī — Rukmiṇī's brother, originally opposed to Kṛṣṇa (he tried to prevent his sister's marriage). His daughter Rukmavatī marries Pradyumna — old enmity dissolved in the next generation. Gauḍīya: bhakti unwinds family feuds.
• duhitaram — the daughter
  Accusative of duhitṛ — daughter. Sanskrit's PIE-cognate word (cf. Greek thugatēr, English daughter). The Rukmī-Rukmiṇī-Pradyumna-Aniruddha cross-marriage knits the families that once warred — Bhagavān's līlā reconciles.

Pradyumna marries his uncle Rukmī's daughter; their son Aniruddha possesses the strength of ten thousand elephants. Generation by generation Bhagavān's potency reproduces — bhakti-aiśvarya is heritable in the line He has chosen.
