01The Images Among the Enemy
Arjuna asks Krishna to drive toward the returning challengers. As the opposing forces close around the chariot, he blows his conch Devadatta and invokes Tvashtra. Thousands of forms resembling Arjuna and Krishna appear. The soldiers cannot reliably distinguish their intended targets from one another and begin striking their own companions.
The confusion creates an opening, but the battle continues. Further volleys obscure the chariot again, and Krishna calls to Arjuna because he can no longer see him. Arjuna then uses a different weapon, Vayavya, to drive away the arrows and the attackers. The account distinguishes the illusion-producing action from the later wind-driven response.
In Drona’s separate fight with Yudhishthira, Tvashtra appears within a series of celestial attacks. Yudhishthira counters the sequence, after which Drona invokes additional weapons. That passage supplies another named use without repeating the detailed illusion scene.
