• skandaḥ — Skanda (Kārtikeya)
  From √skand (to leap, jet forth) — named for the manner of his birth from Śiva's tejas. Commander of the deva-army, lord of war. Even his retreat here is honorable: he yields to a higher power, not to a peer.
• pradyumna-bāṇa-oghaiḥ — by the flood of Pradyumna's arrows
  Compound: pradyumna + bāṇa (arrows) + ogha (flood). The same word bāṇa names both arrows and the demon; the verse plays on this: the demon Bāṇa's domain is being struck down by Pradyumna's bāṇas (arrows).
• śikhinā — on his peacock
  Instrumental of śikhin (one with a crest, i.e. peacock). Skanda's vāhana. The peacock, Kṛṣṇa's own ornament (mayūra-piccha), here serves the retreating son of Śiva — the symbol itself bows toward Vraja.
• apākramat — he retreated
  Aorist of apa-√kram (to step away). Honorable withdrawal, not flight. Gauḍīyas note: Skanda's retreat is the demigod-pattern — when faced with Bhagavān's expansion, the demigod yields without dishonor.

Even Skanda, born of Śiva's tejas to slay Tāraka, retreats before Kṛṣṇa's son. Pradyumna — Kāma-deva reborn in Dvārakā — reminds the cosmos that Kṛṣṇa's family contains every śakti the demigod-family contains, in fuller measure.
