Text

O Arjuna, only another brahmÄstra can counteract this weapon. Since you are expert in the military science, subdue this weapon’s glare with the power of your own weapon.

Purport

For the atomic bombs there is no counterweapon to neutralize the effects. But by subtle science the action of a brahmÄstra can be counteracted, and those who were expert in the military science in those days could counteract the brahmÄstra. The son of DroṇÄcÄrya did not know the art of counteracting the weapon, and therefore Arjuna was asked to counteract it by the power of his own weapon.
