• kṛta-añjaliḥ — with joined palms
  Añjali — palms joined — is the universal Vaiṣṇava posture of supplication. Even a messenger does not address Bhagavān without this gesture. The body says what the words will say.
• para-īśāya — to the Supreme Controller
  The messenger does not address Kṛṣṇa as merely a king but as parameśvara — Supreme Lord. The political appeal is folded inside a theological appeal: it is to Bhagavān, not to a king, that the imprisoned kings cry.
• duḥkham — the suffering
  Bhagavān receives a report of duḥkha. The whole BG begins similarly with Arjuna reporting his duḥkha (BG 1.46-47). Bhakti often starts where pain finds words at Bhagavān's feet.
• nirodha-jam — born of imprisonment
  Nirodha — confinement, blockage — is also the technical term in Bhāgavata cosmology for cosmic dissolution (SB 2.10.1). The imprisonment of the kings is a local nirodha within saṁsāra; only Bhagavān undoes both.

• Whose plea am I in a position to carry forward?
• Where am I called to advocate for those who cannot speak for themselves?

The messenger bowing with joined palms and reporting the kings' suffering is like a single arrow drawn at the foot of the lion. He carries no weapon, only the news of pain — and that, before Bhagavān, is enough to set the rescue in motion.
