• sarva - bhūta - ātma - sākṣiṇaḥ — the witness in the intelligence of all beings
  Sarva (all) + bhūta (being) + ātma (here in the sense of antaryāmin, inner self) + sākṣin (witness). The Paramātmā doctrine in compact form. Nṛga confesses that there is nothing in him not already seen.
• kālena avyāhata - dṛśaḥ — whose vision is unobstructed by time
  Kāla (time) + a-vyāhata (unimpeded) + dṛś (vision). Past, present, future are equally visible to Kṛṣṇa. The phrase rules out any 'forgotten' deed — including the one the king is about to disclose.
• tava ājñayā — by Your order
  Ājñā is the Gauḍīya keyword for the guru's / Lord's command. Nṛga speaks not because he must explain but because Kṛṣṇa has asked. Bhakti operates on ājñā, not on initiative.
• vakṣye — I will speak
  Future of √vac. The willing self-disclosure of a fallen devotee before Kṛṣṇa — the same posture Ajāmila, Prahlāda, and Dhruva each take at the moment of meeting. Speech is the medium of śaraṇāgati.

• What part of my story have I been unwilling to tell because I assume Kṛṣṇa already knows?
• How might speaking it openly in prayer change me, even if it teaches Him nothing?

A child told to recite a story his father already knows still recites it — because the telling is the prāyaścitta, not the information. Nṛga acknowledges Kṛṣṇa's omniscience and then narrates anyway, because confession is for the speaker, not the listener.
