Once Narada Muni, while travelling on planet earth, came across an old hunchback woman.
He felt very kind towards this woman and wanted to fix her back as a boon to her.
So he said to the lady, O Mother, I am very much pleased with you, come here and I will fix your back.
The old lady replied ” O Great Sage, if you are really pleased with me and want to give me some boon, please give me a different boon.
Surprised Narada Muni asked, “What boon would you like to have”.
The old lady replied, “The lady who lives next door to me, please make her also a hunchback.
