• prasannaḥ — satisfied, gracious
  From pra + √sad. Prasāda flows from prasannatā. Gauḍīya note: He is not bargaining — He is already pleased; the straightening is the natural overflow of His already-given grace.
• bhagavān — the Supreme Lord
  The six-fold opulence one: aiśvarya, vīrya, yaśas, śrī, jñāna, vairāgya (Viṣṇu Purāṇa 6.5.47). Used here precisely because what He does next is an aiśvarya display compressed into a tender act.
• darśane — of seeing Him
  Locative of darśana. Gauḍīya doctrine: darśana is not passive viewing — it is reciprocal exchange. The verse calls Kubjā's transformation the phala (fruit) of one such darśana.
• phalam — the result, fruit
  From √phal. Every contact with the Lord bears phala — the verse here makes Kubjā the demonstration-case, the public proof that even an unintended darśana ripens.
• rucira — attractive
  From √ruc, to shine, to please. Even in her crooked state her face was rucira — Gauḍīya commentators note that Kṛṣṇa's mercy descends through the latent goodness already there; nothing is wasted.

A sculptor seeing a piece of warped wood does not throw it out; He turns it on His knee until it remembers its straight form. Kṛṣṇa straightens Kubjā not because she earned it but to show the world what one darśana of Him does to a soul.
