• padbhyām-padma-palāśābhyām — with feet (like) lotus petals
  Phrase: padbhyām (two feet) + padma (lotus) + palāśābhyām (with petals). Vaiṣṇava aesthetics' most precious image — Bhagavān's caraṇāravinda. Gauḍīyas teach that meditation on the lotus feet is the entry-rasa of dāsya-bhakti; Mucukunda's first words honor exactly these.
• vicarasi — You are walking
  Present of vi-√car — to wander, move about. The same root the demigods used for kāla and Kṛṣṇa will reuse in verse 61 ('wander the earth at will'). Bhagavān's vicaraṇa is His freedom — and He gifts the same freedom to His devotee.
• giri-gahvare — in a mountain cave
  Compound: giri + gahvare (cavern). A new word for cave (different from kandara, guhā) — the Bhāgavata vocabulary keeps reframing the same place, like a poet circling the central image. The cave is now Mucukunda's confessional.
• uru-kaṇṭake — full of thorns
  Compound: uru (much) + kaṇṭake (thorny). The cave-floor is rough; Bhagavān's lotus feet should not have crossed it. The motif of Bhagavān's feet wounded for the devotee will return — Rūpa Gosvāmī's verses on Kṛṣṇa's feet bleeding in Vraja's pebbled paths echo here.

  His Holiness Bhanu Swami· English

A man waking in the dark to find someone walking barefoot toward him across a thorn-strewn floor — and the feet are lotus petals. Mucukunda's first thought is concern for those feet. The verse's tenderness is Vaiṣṇava: the bhakta worries for Bhagavān before himself.
