# Dwaraka Established When Kamsa’s two wives complained to their father, Jarasandha, about their husband’s death, Jarasandha decided to attack Krishna. The brothers annihilated his armies, and when Balarama was poised to arrest Jarasandha, Krishna decided to set him free. Krishna wanted Jarasandha to attack multiple times since it would facilitate a large-scale annihilation of his demoniac forces. In total, Jarasandha’s armies were defeated seventeen times. During the eighteenth attack, Narada Muni instigated the wicked Kalayavana and his 30 million soldiers to also join in. The dual attack tipped the scales, and Krishna thus created a magnificent city in the sea (Dwaraka), and mystically transferred the entire Yadava clan there for safety. When Kalayavana pursued Krishna to kill Him, he was led into a mountain cave. In that dark cave, Kalayavana kicked a man he thought was Krishna. That personality stood up and burned Kalayavana to death! This was Mucukunda, who had been awarded the boon of unbroken sleep, and also the power to annihilate anyone who interrupted it. After seeing the beautiful form of Krishna, Mucukunda lamented his absorption in material affairs, and thus requested the divine gift of pure devotional service. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
