When Duryodhana had left, Krishna laughed and asked Arjuna, "what use I could be of in a war? I shall not wield any weapon." Arjuna had an equally hearty laugh. He said, "When you are with us who can think about victory or defeat." You have been our guide throughout. In the war also you shall guide us. You may be my charioteer and my name shall become immortal as you will be called Partha Sarthi.
Like the reins of my chariot the reins of my life are also in your hands. Krishna has decided to act as the charioteer of Arjuna during the war. He came out of his chamber with Arjuna. Satyaki was waiting there anxiously. He felt relieved when he was told that Krishna would be on the Pandavas side. He informed Arjuna and Krishna that Duryodhana had just met Balarama. Satyaki was afraid that Balarama might win over by Duryodhana as he was his favorite pupil. But Krishna allayed his fears. Krishna said that Balarama had asked his opinion. When he told that he wanted to be on the side of the Pandavas. Balarama said that he would not join the war. If Krishna is on the Pandavas's side then victory of the Pandavas is certain. Balarama had lot of affection for Duryodhana, who had all the qualities of a Kshatriya prince. His only weakness was his envy against his cousins, the Pandavas. Balarama said that when Krishna decided to join the Pandavas Duryodhana fate was sealed.
After these discussions they sped towards Upalavya where Yudhisthira was eagerly waiting for the result of Arjuna's embassy to Dwaraka.
GATHERING OF THE ARMIES
Salya heard that the war between the Pandavas and the Kauravas was inevitable. He in the meantime received a messenger sent by Yudhisthira. Yudhisthira wanted his help in the fight against the Kauravas. He had explained that he was fighting for a just cause. Salya left his city with his army of one 'akshauhimi' strong to join Yudhisthira. Duryodhana having got the intelligence about it tried to change Salya's mind. He erected camps on the way of Salya, where his army could take rest and take their food etc. All sorts of lavish refreshments and entertainment's were arranged. Pandavas did not have any idea about Duryodhana plans. Salya and his sons were very pleased with these arrangements. Salya was under the impression that these arrangements had been made by Yudhisthira. He wanted to rewards the servants who had given such an excellent account of themselves.
In place of servants, Duryodhana was there in Salya's camp to his great surprise. When Salya came to know that all the arrangements were made by Duryodhana, he was very pleased with him, Salya said that he wanted to reward the person responsible for these arrangements for his army's comforts, so Duryodhana could ask for whatever he wanted. Duryodhana falling at his feet said, "Only I want your help in the war. Salya was a noble man. Once he had given the words, he was bound by them. He said, "I will fight on your side in the war, but I must go to Upalvya and inform Yudhisthira about it. Also I have to bless my nephews. Duryodhana was very happy. He said, Kindly go to Yudhisthira and then please hurry back to Hastinapaura. Salya went and told the Pandavas about this dilemma. The Pandavas were very unhappy, but Yudhisthira being fair minded undertstood his uncle's problem. The Pandavas sought Salya's blessings. Salya blessed them and said that they would win the war, Then Salya returned. All the allies have now started to arrive. Satyaki, Dhritaketu, Jayatsena, Kekaya brothers, Drupada came with his sons Shikandi, Dhristadhyumma and sons of Draupadi, Virata came with his brothers and sons. Many other kings came. The Pandavas were in command of seven 'akshauhini' of army.
In Hastinapura also armies were gathering. Bhagadatta, Salya, Bhoorishravas, Kritavarma, Jayadratha and many other. Together eleven aksauhinis of army were under Kauravas command.
