I will tell you the story of another beautiful Rajput girl.* There is a peculiar custom in our country called ‘protection’. Women can send small bracelets of silken thread to men. And if a girl sends one of these to a man, that man becomes her brother.
During the reign of the last of the Mogul emperors—the cruel man who destroyed that most brilliant empire of India—he similarly heard of the beauty of a Rajput chieftain’s daughter. Orders were sent that she should be brought to the Mogul harem.
Then a messenger came from the emperor to her with his picture, and he showed it to her. In derision she stamped upon it with her feet and said, ‘Thus the Rajput girl treats your Mogul emperor.’ As a result, the imperial army was marched into Rajputana.
In despair the chieftain’s daughter thought of a device. She took a number of these bracelets and sent them to the Rajput princes with a message: ‘Come and help us.’ All the Rajputs assembled, and so the imperial forces had to go back again.
