• kālanemiḥ — the demon Kālanemi
  The previous incarnation of Kaṁsa. Bhāgavatam's view of asuric continuity: demons return until they are released by Bhagavān's direct action. The chapter's whole metaphysics of birth (verses 36-40) is in service of explaining such reincarnations.
• kaṁsaḥ — Kaṁsa
  Devakī's brother, the central asura of Canto 10. Kṛṣṇa names him by name as a 'past completed action.' The book is recursive — Mucukunda is in the same canto whose protagonists Kṛṣṇa is summarizing.
• pralamba — Pralamba
  The asura killed by Balarāma (SB 10.18). Mentioning him here folds Balarāma's deeds into Kṛṣṇa's own account — the two are non-different in mission, and Kṛṣṇa speaks for both.
• sat-dviṣaḥ — envious of the pious
  Compound: sat (the saintly) + dviṣaḥ (haters). The Vaiṣṇava category for asura — not 'evil' abstractly but specifically 'devotee-haters.' Bhagavān's mission targets those who target His devotees.
• tigma-cakṣuṣā — by the piercing glance
  Compound: tigma (sharp, fiery) + cakṣuṣā (by the eye). Mucukunda's glance is credited inside Bhagavān's own deeds-list. Gauḍīyas treasure this: the bhakta's instrument is the Lord's instrument; Mucukunda's eye-fire is Kṛṣṇa's action accomplished through him.

• Where do you take credit alone for what was collaboration with the Lord?
• How does Kṛṣṇa's crediting His devotee model your own credit-sharing?

Kṛṣṇa lists His current births' work like a soldier reading a brief: Kālanemi reborn as Kaṁsa, Pralamba, others, and now this Yavana — burnt to ash by your glance. He acknowledges Mucukunda's role; the sage's tapas is enrolled into the avatāra's mission.
