(Kadamba Kanana Swami, October 2013, Melbourne, Australia, Srimad Bhagavatam 2.3.12)
At one time, Krsna was establishing that he was the Supreme Lord and that all the various incarnations of the Lord were within him. So the gopis said, “If you are the origin of all the incarnations, then it means that Lord Ramachandra is also here. Lord Ramachandra had an army of monkeys that built a bridge across the ocean. We have monkeys here, we have a body of water. So can you please make a bridge for us?”
And Krsna arranged it. All the monkeys came down from the trees and all picked up stones. They wrote the name of Krsna on these stones and placed them on the water and they floated. Then the gopis walked over the bridge.
So all this is very nice. One who knows this story has a drop of mercy. So many drops of mercy we get from so many different personalities.
