NARAYANA ASTRA
Let us also parallely run through what happens with the pandavas immediately after Drona was killed .
Arjuna was totally against Yudhishtira uttering a falsehood earlier.
Now on seeing his Guru been killed in a very treacherous manner, his sorrows compounded . He was all in tears & feared disaster through Ashwathama .
Drishtadyumna interrupts & speaks some harsh words about Drona & his past which angers Satyaki. A furious Satyaki lambasts Drishtadyumna & challenged him that if he continues with such words about Drona, Satyaki himself will slay Dristadyumna & added that he should feel ashamed to be called a Kshatriya for his sinful act.
An enraged Drishtadyumna continued with his Drona bashing again which further ignited the already sensitive situation.
Drishtadyumna also added further by teasing Satyaki by the manner in which he killed Burisiravas when he was in yoga posture. Satyaki now charged towards Drishtadyumna with his sword & bow with an intention to kill him. However, a timely intervention by Bhima & Krishna saved a big fight between the two.
Sahadeva steps in & pleads to everyone to stand united & face the war & then the Pandavas resumed the war.
As Ashwathama let loose that NARAYANA ASTRA, innumerable number of maces, discs, razor all appeared in the air & it killed those who tried to resist against those weapons. And those multiple weapons destroyed a large chunck of Pandavas & those who tried to resist.
Krishna now quickly addresses the Pandavas :
Speedily lay down your weapons, all of you, and alight from your vehicles. Even this is the means ordained by Narayana himself for baffling this weapon. Come down on the earth, all of you from your elephants and steeds and cars. If you stand weaponless on the earth, this weapon will not slay you. In those places where you will fight for quelling the force of this weapon the Kauravas will become more powerful than you. Those men, however, that will throw down their weapons and alight from their vehicles, will not in this battle, be slain by this weapon. They, however, that will, even in imagination, contend against this weapon, will all be slain even if they seek refuge deep beneath the earth
The warriors of the Pandava army, threw their weapons and drove away from their hearts all desire of battle.
However, Bhima comes up to take the challenge by saying :
None should lay down his weapons here. I shall, with my shafts, oppose this weapon of Drona's son. With this heavy mace of mine, I will destroy this weapon.There is no man here that is equal to me .
Even while Bhima tried to challenge the weapon, the weapon with exceeding energy fell upon the head of Bhima.
However, Krishna rushes to the rescue of Bhima & chides him to put down all his arms & stand without fighting. But for Krishna, Bhima would have lost his life at that moment.As Bhima reluctantly did it, the Narayana weapon, became pacified.
Duryodhana urges Ashwathama to fire the Narayana weapon again but he refuses by saying that it will be counter productive if it is applied again.
Cheerlessly, the Kaurava army finally move towards their tents for rest
AND FINALLY THAT DREADFUL 14TH DAY OF THE WAR CAME TO A CLOSE
