• ākranditam — the crying out, lamentation
  From ā-√krand — to cry, weep aloud. The same root produces krośantam in v. 26 when the gopīs cry out for rescue. Vraja's cry-to-Kṛṣṇa pattern is being set up here in the father, to be echoed later in the gopīs.
• vibhrāntāḥ — bewildered, agitated
  Vi-√bhram — to be tossed about, deranged. Even gopas who have lived with Kṛṣṇa daily lose their composure when their leader is in danger. Affection (sneha) outruns equanimity — a feature of Vraja-bhāva, not a flaw.
• ulmukaiḥ — with firebrands, blazing torches
  Ulmuka = burning torch. The cowherds use the only weapon a night-camp affords. Gauḍīyas read it as ordinary effort: the devotee fights for the devotee with whatever tools are at hand, even while knowing Kṛṣṇa alone is the real rescuer.
• vivyadhuḥ — they pierced, struck
  Perfect of vi-√vyadh — to strike hard, pierce. The vigor of the cowherds' assault is recorded so that the snake's continued grip in v. 8 will throw Kṛṣṇa's effortless touch into sharper relief.

The cowherds wake, see Nanda half-swallowed, and beat the snake with blazing torches — like village fathers fighting fate with what is at hand. But fate, when it is karma made flesh, does not release for fire. Only the foot of Bhagavān unlocks that mouth.
