The Pandavas and Krishna who were away during night (when Ashwatthama attacked on Pandava Camp), now returned to their camp the next day morning. Hearing the news of these events in the morning Yudhishthira fainted and the Pandavas become inconsolable. The Pandavas went searching for Ashwatthama to sage Vyasa’s ashram. On seeing the approaching angered Pandavas, Ashwatthama as a last resort, devised a Brahmashirsha astra from a blade of grass and invoked it against the Pandavas and Krishna. Arjuna invokes the same astra, which he received from Drona himself, towards Ashwatthama. Narada and Vyasa came to stop Brahmashirsha astra used by Ashwatthama and Arjuna. On seeing the two powerful astra’s heading for a head on cataclysmic (catastrophic) collision that would result in the total annihilation of the entire Earth, Vyasa stopped these divine weapons from colliding with each other by using his yogic power. He asked both these warriors to withdraw their respective weapons. Arjuna was able to withdraw his Brahmashirsha astra, while Ashwatthama could not do so as Drona did not teach his son how to withdraw it, thus limiting the power of Ashwatthama to use the astra for only one instance. Ashwatthama was given the option of deviating his weapon towards and uninhabited place, so that the astra could explode harmlessly. Out of rage, Ashwatthama instead directed the weapon towards the womb of the pregnant Uttara in an attempt to end the lineage of the Pandavas. The angered Pandavas wanted to kill Ashwatthama, but Sage Vyasa reminded them of the deceitful tactics they had used against the Kauravas. As a punishment, Ashwatthama was asked to surrender the gem on his forehead. Krishna then cursed Ashwatthama for 3000 years that he will roam in the forests with blood and puss oozing out of his injuries and cry for death . Since he had no fear of death during war, death would not meet him. He will have neither any hospitality nor any accommodation; he will be in total isolation without any contact of physical communication from mankind and society. The wound caused by the removal of this gem on his forehead will not heal and his body will suffer from a host of incurable diseases forming sores and ulcers that would never heal for 3000 years.
