Can you tell me about the devotee who was advised to feed ants and what happened during a robbery?

The devotee you're referring to is Kashiram. According to the narrative in Chapter 0, he was advised by a saint named Janakidas Baba to feed sugar to ants. Because of this, Kashiram always carried a bundle of powdered sugar, which he considered very precious. This practice became central to a dramatic incident where he was attacked by Bhil robbers. The robbers mistook his bundle of sugar for treasure and tried to steal it. As the text explains, Kashiram was so devoted to his vow that he decided he would not let the bundle go, leading him to fight back fiercely. He picked up a dropped sword, killed two thieves, and was then struck unconscious by a third, highlighting his extreme dedication.
