BHISHMA TRIED TO INJURE LORD KRISHNA

Lord Krishna decides to raise his weapon Chakra against Bhishma

Being the remarkable warrior Bhishma used to be unstoppable in the Mahabharata war. It was not possible to defeat or kill him. Lord Krishna became indignant about him during the Mahabharata war and thought of killing him all by himself. We all remember lord Krishna  stating not to raise weapons in the war, then what made him change his mind? What exactly had happened that made him take such a step?

On the third day of the Mahabharata war, brave Bhima made Duryodhana unconscious by way of shooting an arrow at him. Seeing Duryodhana being senseless his armies started out running here and there out of fear. Even his Pitamaha: the commander in chief Bhishma and Acharya Drona could not stop the army of Duryodhana. Pandavas alongside other kings like Dhrishtadyumna, Satyaki terrified the armies thereby shooting many arrows at them. 

After gaining back his consciousness, Duryodhana again got his army back on the battleground, went to Bhishma Pitamaha, and told him, "Regardless of having Great warriors like Bhishma Pitamaha, Dronacharya, Kripacharya and Ashwathama, my armies ran away and many have been destroyed. Pitamaha! If you  had to exhibit mercy to the Pandavas and no longer to battle with Dhrishtadyumna, Satyaki all through the warfare then you could have confirmed it to me earlier than the beginning of the war only." Then he asked Bhishma and Drona to show their heroism in the war unless they think leaving behind Duryodhana would be splendid at that time.

Hearing such from Duryodhana, Bhishma referred to him that, winning over Pandavas was not even possible by great deity like Indra. However being provoked by Duryodhana, Bhishma all by himself attacked and killed a huge number of Pandavas' armies furiously. A massive number of Yudhishthira's army got scattered, many elephants, horses had been injured and chariots had been destroyed by Bhishma.  Seeing the frightened army of Yudhishthira, Lord Krishna told Arjuna to fight with his full force. Arjuna went in the direction of Bhishma.

Seeing Arjuna coming, Bhishma shot many arrows at his chariot which injured the horses. However lord Krishna being the charioteer of Arjuna did not get distracted and tactfully reached close to Bhishma. Arjuna broke his Dhanush whilst shooting back at him. Bhishma was thrilled with the promptness of Arjuna, took another Dhanush in his hand, and challenged Arjuna to combat with him. Bhishma wounded Arjuna along with Lord Krishna deeply via shooting many arrows at his body. Enraged Bhishma blocked both of them on their chariot by raining  thousands of arrows on them. Bhishma then continuously shot many arrows whilst laughing loudly out of exasperation and tormented as well as staggered Lord Krishna.

Lord Krishna knew that even after badly harming  Arjuna and after Destroying many soldiers of Yudhishthira, Arjuna was still fighting with Bhishma while maintaining a soft heart towards him. Lord Krishna could not tolerate seeing the destruction of the Yudhishthira's army. Krishna knew that Bhishma was capable enough to even defeat the whole deities and demons in a single day. Noticing the complete army of Pandavas running away everywhere, Lord Krishna thought of killing Bhishma all by himself and reliving the religious Pandavas from their miserable situation. He was aware that Being respectful towards Pitamaha, Arjuna used to be not following his duties. Satyaki observed Arjuna being surrounded via Gajraj armies and many armies of Kauravas. He came to assist the armies of Pandavas and additionally reminded them of their  Kshatriya dharma to fight bravely instead of running away from there.

That time Lord Krishna determined to defeat the whole Kauravas and to please Pandavas. He remembered his divine weapon Sudarshan chakra and it regarded on his hand. While having the chakra on his right hand he jumped off the chariot and with an intention if killing Bhishma rushed in the direction of him whilst trembling the whole earth. He was capable of killing the entire Kauravas. Seeing the glory of furious Lord Krishna in this form Kaurava armies lamented and mourned there. Bhishma was not at all terrified by noticing Lord Krishna coming closer to him. He offered his prayers to Krishna and gladly waited for his death. Bhishma knew that it would be a splendid fortune for him to die at the hands of Narayana.

Arjuna went after Lord Krishna immediately and tried to stop him by grabbing Lord's both arms. But lord used to be so angry that time he did not stop and went further. Then Arjuna forcibly hold the toes of Lord Krishna and made him stop. After that Arjuna pacified the anger of Lord Krishna and promised that he himself would fight with Bhishma with all his efforts.
