• durabhiprāyān — with evil intent
  Compound: dur (bad) + abhi (toward) + prāya (intent). The Bhāgavata names the guards' intent. Gauḍīya doctrine: the Lord acts only against durabhiprāya, never against ignorance alone. His violence is precision-targeted.
• bala-keśavau — Balarāma and Kṛṣṇa
  Contiguous compound: Bala (Balarāma) + Keśava (Kṛṣṇa). Dual. The two brothers act in concert. Gauḍīya: Balarāma is named first — agra-ja's precedence preserved even in combat.
• kruddhau — angry
  Past participle dual of √krudh. Both become angry. Gauḍīya note: Bhagavān's krodha is dharma-krodha — not vyākulatā but rakṣaṇa, protective fierceness. Different in kind from the kupitāḥ guards of verse 19.
• śakale — the two broken pieces
  Locative-dual of śakala — fragment. The two halves of the bow. Gauḍīya commentators savor the detail: what the enemy worshiped becomes, in pieces, what kills him. The Lord uses His enemies' offerings against them.
• jaghnatuḥ — the two of Them struck
  Perfect dual of √han. The verb of killing. The Bhāgavata reserves √han for sacred violence — Kṛṣṇa's hananam is not crime but cosmic re-balancing.

• Where could a broken piece of your life still serve as a weapon in His hand?
• What 'half-bow' have you discarded that Kṛṣṇa might still pick up?

A surgeon's instruments shattered mid-operation become themselves the tools by which the surgery is finished. The very bow whose worship was Kaṁsa's defense becomes, in two halves, the weapon of his guards' destruction. Kṛṣṇa improvises with the wreckage of the enemy's reverence.
