This is the most visceral image in the entire Gita. Warriors do not walk calmly to their end. They rush. They hurtle headlong into the gaping, fanged mouths as though drawn by a force they cannot resist. And some — some are caught between the teeth, their heads ground to powder.
There is something deeply unsettling about the word 'tvaramanah' — rushing, hurrying. These warriors are not being dragged. They are running toward their destruction with speed, almost eagerness. Like moths that do not slow down as they approach the flame. The pull of Time does not wait for consent.
Arjuna sees this and he knows these men. He has trained with them, eaten with them, fought beside them. The crushed heads between those cosmic teeth are not anonymous. Each one belongs to someone Arjuna could name. This is not a philosophical abstraction about mortality. It is happening before his eyes, to people he loves.
