The Padmavyūha (Sanskrit: पद्मव्यूह) or Chakravyūha (चक्रव्यूह) refers to a Military formation narrated in the Hindu epic Mahabharata.
The Chakravyūha or Padmavyūha, is a multi-tier defensive formation that looks like a blooming lotus (padma, पद्म) or disc (chakra, चक्र) when viewed from above. The warriors at each interleaving position would be in an increasingly tough position to fight. The formation was used in the battle of Kurukshetra by Dronacharya, who became commander-in-chief of the Kaurava army after the fall of Bhishma Pitamaha.
The various vyūhas (military formations) were studied by the Kauravas and Pandavas alike. Most of them can be beaten using a counter-measure targeted specifically against that formation. It is important to observe that in the form of battle described in Mahabharata, it was important to place the powerful fighters in those positions where they could inflict the maximum damage to the opposing force, or defend their own side. As per this military strategy, a specific stationary object or a moving object or person can be captured and surrounded and rendered fully secured during time of military conflict. The pattern is of two soldiers on both sides with other soldiers following them at a distance of three hands, drawing up seven circles and culminating in the end which is the place where the captured person or object is to be kept. In order to make Chakravyuha, the Commander has to identify soldiers who will form this formation. The number of soldiers to be deployed and the size of the Chakravyuha is calculated as per the resistance estimated. Once drawn, the foremost soldiers come on either side of the component to be captured, engage briefly and then move ahead. Their place is taken up by the next soldiers on either side, who again engage the component briefly and then move ahead. In this fashion, a number of soldiers keep on passing the component and keep on moving in a circular pattern. By the time the last bit of soldiers arrive, the component, oblivious of the design is captured within seven tiers of soldier formation surrounding him from all sides. The last soldiers of the formation give the signal of completing the Chakravyuha. On the signal, every soldier who so far has been facing outwards, turn inwards to face the component. It is only then that the captured component realizes his captivity. The Chakravyuha keeps on moving in a spherical order and can easily lead the component away in captivity as well.
