• vṛkodaraḥ — Bhīma
  Nominative. Kṛṣṇa points to Bhīma first — he is the actual fighter. The introduction order matters: combatant first, second second, then Himself as orchestrator.
• pārthaḥ — the son of Pṛthā
  Nominative. Both Bhīma and Arjuna are 'Pārthas'. Their mother Pṛthā is Kṛṣṇa's paternal aunt — making them Kṛṣṇa's maternal cousins, which the next phrase makes explicit.
• mātuleyam — the maternal cousin
  Accusative. Mātula — maternal uncle; mātuleya — his son. Kṛṣṇa locates Himself in the family tree precisely; the kinship is real and binds Him to take part in the Pāṇḍava cause.
• ripum — enemy
  Accusative. Kṛṣṇa names Himself as Jarāsandha's enemy openly. Note the Gauḍīya reading: even when Bhagavān is named enemy, He grants the rare gift of dying by His arrangement — śatru-bhakti through hatred ends in liberation.

• Where can I drop a disguise now that has served its purpose?
• Is there a truth about who I am that's now ready to be plainly stated?

An archer who has fooled a king into committing the bow's draw now identifies himself: 'I am the brother of the wind and son of the sun's cousin, and I am Kṛṣṇa, your enemy.' The mask falls; the bowstring is already taut.
