• atha — then
  Inceptive particle. The Bhāgavata uses atha at decisive turns. The skirmish is over; the duel of the principal warriors begins. The whole chapter's narrative weight tilts on this small word.
• śauriḥ — Lord Kṛṣṇa
  Patronymic from Śūrasena (Vasudeva's father's father). Gauḍīyas note Śuka's choice: not Hari or Govinda but Śauri — Kṛṣṇa as descendant of the great Yadu warrior lineage. The name evokes the kṣatriya backbone of the present action.
• astrāṇi — weapons
  Plural of astra (missile). In dhanurveda an astra is a weapon empowered by mantra — not merely material. Kṛṣṇa says He is releasing astras at the man who asked for them. The poetic logic: Pauṇḍraka named these weapons in verse 8 as his own; Kṛṣṇa now demonstrates whose they are.
• utsṛjāmi — I am releasing
  Present of ut-√sṛj (to release upward). Echoes the future utsrakṣye of verse 8: what Kṛṣṇa promised, He now does in real time. Bhagavān's word and act are unseparated — the simplest definition of His truthfulness.
• dūta-vākyena — through the words of the messenger
  Compound instrumental: dūta (messenger) + vākya (statement). Kṛṣṇa names the exact channel of Pauṇḍraka's earlier speech. Gauḍīyas note: even in mocking, the Lord respects the genealogy of the words — He returns them via the same conduit that delivered them.

A teacher hands back the student's own essay, marked through and corrected, with the line: 'Here is what you asked Me to consider — now consider it Mine.' Kṛṣṇa returns Pauṇḍraka's words and weapons to him with interest.
