• hariṇā — by Lord Kṛṣṇa
  Instrumental of Hari — He who steals (harati) the hearts of His devotees and the sins of the surrendered. Even when fleeing, Kṛṣṇa is the active agent; Kālayavana imagines he is the hunter, but Hari is the one leading.
• pade pade — at each step
  Reduplication for emphasis — at every single footfall. Bhagavān's līlā is not coarse-grained; He calibrates each step so that the asura's hope is renewed and then frustrated, drawing him exactly to Mucukunda's cave.
• darśayatā — by Him who was showing
  Present participle of √dṛś, causative. Kṛṣṇa is darśayitā — the One who shows. He shows Himself as catchable so He can show Mucukunda as the burner. Every darśana He grants is itself a teaching.
• yavana-īśaḥ — the king of the Yavanas
  Compound: yavana (barbarian, foreigner) + īśaḥ (lord). Kālayavana is 'lord' of the mlecchas but is being led like a beast by the actual Īśvara. The repeated īśa-vocabulary in this chapter is deliberate — Mucukunda will later use īśa for Kṛṣṇa, contrasting true lordship with pretended lordship.
• kandaram — cave
  The cave is Bhagavān's chosen instrument. Gauḍīyas read this as a paradigm: Kṛṣṇa pre-arranges the geography of His līlā so that the devotee Mucukunda — sleeping for ages — is exactly where He needs him at the precise moment. Nothing in His pastimes is accidental.

• Where do you imagine yourself pursuing when you are actually being led?
• How could the cave you're heading toward be the Lord's plan?

A cowherd leading a strong but blind bull by holding a stick just past its horns — always within reach, never reached. Kṛṣṇa lets His hand seem to brush Kālayavana's grasp at every step, drawing the doomed king exactly to the cave-mouth He has chosen. The 'flight' of Bhagavān is a route, not a retreat.
