Bhishma’s lone conch blast in the previous verse was a signal. Now the entire Kaurava army responds. Every instrument of war — conches, kettledrums (bherya), small drums (panava), war drums (aanaka), and the distinctive cow-faced horns (gomukha) — sounds simultaneously. The word sahasaiva tells us this happened all at once, in a sudden, overwhelming surge of noise. The result is described as tumula — tumultuous, chaotic, beyond individual distinction.

This verse functions as a cinematic moment of escalation. The single roar of one great man has ignited a chorus of thousands. What began as one warrior’s act of loyalty and reassurance has cascaded into the full-throated war cry of an army that numbers in the hundreds of thousands. There is no going back now. The instruments of war have spoken.

The range of instruments named here reflects the rich military culture of ancient India. The shankha (conch) was associated with divine warriors and carried ritual significance. The bherya were the great kettledrums that could be heard for miles, used to coordinate troop movements. The panava and aanaka were smaller percussion instruments that maintained rhythm during the advance. The gomukha — literally “cow-faced” — was a brass horn shaped like a cow’s head, its deep resonance designed to carry across vast distances.

Taken together, the instruments represent all dimensions of the sonic battlefield: the sacred (conch), the tactical (drums), and the terrifying (horns). Ancient battle doctrine understood that sound was itself a weapon — it could demoralize enemies, inspire soldiers, and create the psychological conditions for victory before a single sword was drawn.

For the reader or listener of the Gita, this verse marks a threshold. The talking is over. The scene-setting is complete. The war is about to begin. And it is in precisely this moment — surrounded by this deafening, irreversible tumult — that Arjuna will ask Krishna to drive the chariot to the center, will see his kinsmen arrayed for battle, and will break.

This verse is part of the Bhagavad Gita’s first chapter, Arjuna Vishada Yoga — the Yoga of Arjuna’s Despondency.
