• aśubham bhuñje — I shall enjoy / suffer the impious (reactions)
  Aśubha (inauspicious) + bhuñje (I experience, from √bhuj). Spoken with the opening pūrvam (first), Nṛga elects to face the debt before the dividend. Gauḍīyas commend the choice as the dharmic king's instinct: settle the karma-debt now, taste piety afterward. Yet the choice does not nullify the fall.
• pata iti — fall, thus
  Single imperative pata from √pat (to fall), followed by iti. The most economical sentence in the chapter. The whole svarga is voided in one syllable — pata.
• adrākṣam ātmānam kṛkalāsam — I saw myself as a lizard
  Adrākṣam (I saw, aorist of √dṛś) + ātman (self) + kṛkalāsa (lizard). The king watches his own form change mid-fall — a striking detail. The ātman persists; the upādhi (body) changes; Gauḍīyas read this as exact-Bhāgavata anthropology.
• patan prabho — while falling, O master
  Patan (present participle of √pat) + prabho. Even narrating his own fall, the king cannot finish the sentence without a vocative for Bhagavān. The reflex of address is bhakti's own grammar.

A wise traveller, given the choice of bitter herb or sweet, takes the bitter first so the journey ends in sweetness. Nṛga's choice is the king's choice in saṁsāra: clear the debt first, even at the cost of the immediate body. Even so, the fall is real — he watches his own descent.
