JARASANDHA’S BATTLES

Obsessed with the desire to kill Lord Krishna, the demon Jarasandha repeatedly attacked Mathura with massive armies of demonic soldiers.
Great battles ensued in which Lord Krishna destroyed Jarasandha’s entire armies.
At the end of each battle, Lord Balarama captured Jarasandha and bound him with the ropes of Varuna. Then, the Lord released Jarasandha and sent him home, where the demon again assembled another vast army with which to attack Mathura.
Krishna was pleased by Jarasandha’s repeated attacks because they facilitated and expeditedHis mission of killing all the demons in the world.
