• vidyudbhiḥ — by bolts of lightning
  From √vid (to know, shine). Lightning — sudden, terrifying, revealing. In the līlā it sets off Kṛṣṇa's dark form for the gopīs; here it is bent into a weapon. Same element, opposite use.
• stanayitnubhiḥ — by thunder
  From √stan (to roar, resound). The Vraja-poets use the same verb of the cow's affectionate lowing; Indra's clouds borrow the sound and weaponize it. The rasa-vocabulary itself is being attacked.
• jala - śarkarāḥ — hailstones
  jala (water) + śarkarā (gravel, sugar-crystal). Frozen rain hurled as stones. The same water that nourishes Vraja's grass and the gopīs' kuṅkuma-mixed bath becomes weapon — a small parable of any energy untethered from Kṛṣṇa.
• tīvraiḥ — fearsome
  From √tij — sharp, intense. The adjective accumulates with marut-gaṇa, vidyut, stanayitnu — the verse stacks intensifiers to mark this as no ordinary storm but a borrowed pralaya. Gauḍīya reading: the offender always over-reaches.

The clouds whip with lightning and thunder and hail, like a master overseer driving slaves — but the slaves they drive are the very elements Kṛṣṇa speaks of in Bg 7.4 as His separated energies. Every bolt of lightning is the Lord's borrowed light, turned briefly against His own home.
