The story is about Krishnadevaraya again. One day he woke up after dreaming of a beautiful floating palace in the clouds. He wanted to make it a reality, and one of his ministers agreed to do it. The King followed up after a few weeks, but the minister was just lazying away. Then after a few weeks, an old man came who claimed that he was a merchant who was looted. The man said he had seen in his dream, his house and family being looted by the King and his ministers. The King was angry and asked how that could happen. This is when he realised that it was Tenali Raman dressed as an old man so that he could teach the King a lesson.
Moral of the story : It is always best to not chase after impossible dreams.
