तस्मिन् सुतुमुले युद्धे वर्तमाने भयावहे
tasmin sutumule yuddhe vartamāne bhayāvahe
Sañjaya said: As that exceedingly tumultuous battle was unfolding—terrifying in its very nature—
संजय उवाच
The line foregrounds the moral atmosphere of war: when violence becomes 'sutumula' (overwhelmingly chaotic) and 'bhayāvaha' (fear-producing), dharma is tested not in theory but amid terror and confusion—setting the stage for choices made under extreme pressure.
Sañjaya, the battlefield narrator, marks a transition: he describes that the battle has become intensely tumultuous and frightening, preparing the listener for the ensuing events and actions that occur within this heightened crisis.
