A "mighty" king imprisoned in a mountain . . . . from the 'Gita

Q: Who is Jarasandha?

The kings and the princes released by Lord Krsna after the death of Jarasandha were rulers of different parts of the world. Jarasandha was so powerful in military strength that he had conquered all these princes and kings, numbering 210,800. They were all incarcerated within a mountain cave especially constructed as a fort, and for a long time they were kept in that situation. When they were released by the grace of Lord Krsna, they all looked very unhappy, their garments were niggardly, and their faces were almost dried up for want of proper bodily care. They were very weak due to hunger, and their faces had lost all beauty and luster. Becacuse of the kings' long imprisonment, every part of their bodies had become slackened and invalid. But although suffering in that miserable condition of life, they had the opportunity to think about the Supreme Personality of Godhead, Visnu/Krsna/Brahma.
