• vīra-manaḥ-harām — enchanting to heroes (lit. carrying away the minds of heroes)
  Compound: vīra + manaḥ + harām (from √hṛ, to seize). The word manaḥ-harā is used in poetics for the heroine who captivates the hero. Subhadrā is named here as the manohara of vīras — a Kṛṣṇa-related power, since attraction to Bhagavān's parikara is no ordinary lust.
• kanyām — the girl
  From kan (to be pleased, to desire). A maiden. Subhadrā as kanyā is at the threshold — between brother's house and husband's. Gauḍīyas note that kanyā in śāstra always implies a yogyā-pātra (suitable receiver) for one designated by elders.
• bhāva-kṣubdham — agitated with emotion
  Compound: bhāva (emotion, here laukika-rati) + kṣubdham (agitated, from √kṣubh). The same root the verse uses for Balarāma's anger in v. 11 (kṣubhitaḥ) — the chapter chains together the kṣobha of lover and brother, both pacified eventually by Kṛṣṇa.
• utphulla — blossoming
  From ut + √phull (to bloom). The eyes 'bloom' — a stock alaṅkāra for the moment of darśana. Gauḍīyas use the same verb when devotees first see Bhagavān — phulla-padma-nayana, lotus-eyes blossoming.

Arjuna's eyes open like lotuses at dawn — but the sun here is Subhadrā, Kṛṣṇa's own sister. The pārtha who once needed Kṛṣṇa to lift his bow on Kurukṣetra now needs Kṛṣṇa to sanction his own heart.
