• rāmam — Balarāma
  Kṛṣṇa's elder brother and source of all strength (bala). Gauḍīyas treat Him as svayam Saṅkarṣaṇa, the original cause of all incarnations. Kṛṣṇa's appeal to Balarāma's invincibility is doctrinally exact, even as it serves the role of grief.
• asambhrāntam — not bewildered
  Compound: a (not) + sambhrānta (confused). The very word Kṛṣṇa used in v. 10 about Dāruka — "do not be bewildered" — He now applies to Balarāma. Sambhrama is foreign to the Lord and His direct expansions.
• alpīyasā — by an insignificant one
  Comparative of alpa — extremely small. Kṛṣṇa's chosen adjective for Śālva even inside the staged grief — exposing that, role or no role, He cannot quite call the demon great. The grief is real-seeming; the assessment is true.
• bala-vān-vidhiḥ — powerful fate
  Phrase: vidhi (destiny) + bala-vān (strong). Kṛṣṇa publicly invokes vidhi — Gauḍīyas read this as the perfect ham-actor's flourish: Bhagavān, the very Vidhātṛ, names vidhi as His superior, completing the human-grief tableau.

• Where am I performing composure I do not feel?
• What would it mean to let myself respond honestly to news that lands hard?

"Balarāma is ever-vigilant, unconquerable by demigod or demon. How could trivial Śālva defeat Him and abduct My father? Indeed, fate is all-powerful!" Kṛṣṇa's response inside the staged grief still cannot quite let go of the truth — He notes loudly that the report is impossible, then concedes vidhi. The Lord's role-playing remains transparent.
