• ari-vadha-upāyam — the means of killing the enemy
  Compound accusative. Three-stem compound. Ari (enemy) + vadha (killing) + upāya (means). The verse compresses the strategic problem and its solution into one noun.
• amogha-darśanaḥ — of infallible vision
  Compound nominative. Amogha — never wasted, never missing. Kṛṣṇa's seeing always lands its target. The epithet appears precisely when His seeing identifies the weak seam in Jarāsandha's anatomy.
• viṭapam — a tree branch
  Accusative. A twig — small, ordinary, available. The smallness is the point: Bhagavān teaches deep secrets through small things. The Vraja-līlā is full of this — a flute, a rope, a peacock feather.
• pāṭayan-iva — as if tearing apart
  Participle + iva. The 'as if' is preserved — Kṛṣṇa does not break the twig openly, merely as if. Subtlety is the medium of the message.
• saṁjñayā — as a sign
  Instrumental. Saṁjñā — sign, signal. The whole communication happens through a saṁjñā. Cf. saṅketa in Vraja — Kṛṣṇa's signals to the gopīs through flute-notes.

• What small sign from the Lord might I have missed because I was waiting for speech?
• How is my eye trained to receive Kṛṣṇa's gestural guidance?

A general signals with a flag, a coach with a whistle. Kṛṣṇa signals with a torn twig — pādayan iva, 'as if tearing' a branch in half. The smallest gesture conveys the deepest secret. Bhīma reads the leaf and reads Jarāsandha's anatomy.
