Three men were stranded on an uninhabited island. The only way back home was to swim 100 miles to the next island, which was inhabited.
Herolal was so determined to get home that he tried to swim. He made it 50 miles, got tired, and drowned.
Then Pyarelal tried. He made it 75 miles, but got tired and drowned, too.
Bhola thought he could make it all the way, so he started swimming. He swam 50 miles, but started getting tired, so he swam all the way back to the island.
