• balasya — of Lord Balarāma
  Genitive of bala. Gauḍīya: the verse credits the entire cascade to Balarāma's līlā — His pastime, not His effort. Even forest-scale destruction is leisurely from His side.
• līlayā — as the pastime
  Instrumental of līlā. Gauḍīya: the central Gauḍīya term for divine action. Līlā means play — purposeless from saṁsāra-view, sva-prakāśa-ānanda from theology-view. Nothing the Lord does is grim; everything is līlā.
• khara-deha — by the body of the ass
  khara (ass) + deha (body). The asura-body, now a projectile. Gauḍīya: the body Dhenuka cultivated to obstruct the grove ends as the trigger of its release; karma turns against itself in the Lord's hand.
• hata-āhatāḥ — which were striking one another
  hata (struck) + āhata (struck again). Reduplication for repeated action. Gauḍīya: the cascading trees both kill and are killed in the same instant — the līlā compresses cause and effect.
• mahā-vāta īritāḥ iva — as if blown by a powerful wind
  mahā-vāta (great wind) + īrita (driven) + iva (as if). The Bhāgavatam's simile. Gauḍīya: the iva is important — there IS no wind; Balarāma's līlā substitutes for cosmic forces. He is the unseen vāyu of this moment.

A great storm wind moves through a grove — the trees beat each other, hata-āhatāḥ, striking and being struck. Here there is no wind; the agent is the līlā itself. Balarāma's single throw produces wind-class consequence. The verse's simile is precise: mahā-vāta-īritāḥ iva — as if blown by a powerful wind. The Lord's hand IS the wind for one moment.
