Yadavas went to Hiranmaya-khanda, where many monkeys lived, led by Nila and Nala, who received their kingdom in Treta-yuga from Lord Rama. When the monkeys saw the warlike Yadava army, they decided to fight and rushed to the attack. Wrapping with tails the chariots, they easily threw them into the sky. However, Hanuman, who was present at the flag of Arjuna, seeing the behavior of these monkeys, became very angry. Appearing there, he embraced all the monkeys with his mighty tail and threw them to the ground. Then the monkeys immediately recognized him and surrendered to his feet in great humility. The king of this province, Devasakha, voluntarily paid a rich tribute to Pradyumna.

Kalanka
Yadavas went to Ramyaka-khanda. Kalanka, son of Kalanemi, came to this place from Lanka in Treta-yuga for fear of Rama. Black Kalanka decided to fight the Yadavas, and therefore saddled his donkey. In that battle between the demons and the Yadavas, the huge Kalanka grabbed chariots and soldiers with his mouth and swallowed them. Praghosa, the son of Krishna, released his kapindra weapon and from this weapon came Hanuman, who grabbed Kalanka and threw him eight hundred miles away. Kalanka recognized Hanuman and threw a heavy club at him. Hanuman dodged the club, and fierce duel began between them. In the end, Hanuman lifted the mountain and brought it down on the demon, taking his life. Having slain the Kalanka, Hanuman disappeared mystically.
