• bhasmī-kṛtaḥ — turned to ashes
  Compound: bhasma + kṛtaḥ. Fourth use of bhasma-related vocabulary in the chapter — 12, 22, 50, here. The Bhāgavata pins the chapter together with this word; Kālayavana's combustion is the structural pivot.
• ātmīyena — by his own
  Adjective from ātman + īya — pertaining to his own self. Mucukunda diagnoses correctly: the asura's pāpa was 'his own' — not the sage's wrath. Bhakta's discernment: see whose karma is at work.
• pāpmanā — by sinful karma
  Instrumental of pāpman — sin-quality. The cause is named: pāpa, not tapas. Gauḍīyas note: a tapasvī's glance does not, of itself, burn — the asura's accumulated aśubha (verse 8) is the actual fuel.
• śrīmān — glorious, possessed of śrī
  From śrī. He whom Lakṣmī accompanies. Mucukunda's first epithet for Kṛṣṇa post-darśana names the inseparability of Bhagavān and śrī — the Vaiṣṇava theological commitment that Lakṣmī never leaves Viṣṇu's side.
• amitra-śāsanaḥ — the chastiser of enemies
  Compound: amitra (non-friend, enemy) + śāsanaḥ (the one who disciplines). Bhagavān's executive aspect. Even before Mucukunda calls Him Nārāyaṇa, he calls Him the punisher of asuras — true to his kṣatriya idiom.

• Where does the same event you experience as awakening burn another's life — and what does that reveal?
• How do you steward your karma so that interruptions become alarms, not ashes?

Mucukunda summarizes the moment: one man was burned away by his own karma, and immediately, in the same gaze, You appeared. He recognizes the sequence — Bhagavān often follows on the heels of the asura's combustion. The cave was emptied for Him.
