• bhagavān — the Supreme Lord
  The first time in this combat-sequence that Śuka uses the full title Bhagavān — six aiśvaryas in one word (jñāna, vīrya, yaśas, śrī, vairāgya, aiśvarya). Placed exactly at the killing-stroke to remind the reader that what looks like a wrestler-trick is a Bhagavān-act.
• madhu-sūdanaḥ — the killer of the demon Madhu
  An ancient title rolled forward into the Canto 10 līlā. Gauḍīya bhakti reads such names as portable testimony: every name of Kṛṣṇa carries an episode of protection, and chanting them invokes that protection now. A contiguous-token join of synonyms 'madhu' and 'sūdanaḥ'.
• nigṛhya — firmly seizing
  Active grasp — the verb shifts. Earlier Kṛṣṇa slipped from the elephant's grip (vigalitaḥ, 43.6); now He does the gripping. Bhagavān's hand on the demon is the hand of Yamarāja in disguise.
• bhū-tale — onto the ground
  The same earth on which the tusks struck two verses ago now receives the elephant himself. Bhū-devī, who has waited the whole Canto, takes the body of her tormentor at last. A contiguous-token join of synonyms 'bhū' and 'tale'.

Kṛṣṇa is here named Madhusūdana — slayer of the demon Madhu — and the name appears at the precise moment His one hand brings down the elephant. Whatever demon stood at the dawn of creation, the same Lord stands at the gate of Mathurā; the hand is one hand, the work one work.
