द्रोणपर्व — अध्याय १६२: प्रातःसंध्यायां युद्धप्रवृत्तिः तथा रजोमेघे संमूढता
एवमुक्तास्तु ते सर्वे शस्त्रवृष्टीरपातयन्
evam uktās tu te sarve śastravṛṣṭīr apātayan
Sañjaya said: Thus addressed, all of them at once unleashed a rain of weapons.
संजय उवाच
The line highlights how, in the momentum of war, speech (orders, provocation, or counsel) rapidly becomes action; it implicitly contrasts disciplined restraint with the ease of collective escalation into violence.
After being addressed (by a prior speaker in the episode), the assembled warriors respond immediately by hurling weapons in mass, described metaphorically as a ‘rain’ of arms.
