Chakra Vyuham: The Trap Formation That Turned Battlefield Geometry into Psychological Warfare
The original Mahabharata passages describe the formation as a firm, fierce, foremost and impenetrable circular array formed by Drona. Abhimanyu openly says he has been taught by Arjuna how to penetrate and strike such an array, but he also admits that if danger overtakes him, he does not know how to come out. This single admission gives the episode its entire military depth: Abhimanyu has entry knowledge, but lacks complete exit doctrine.
