Yes, the source material does mention another holy person. During the account of Kashiram's encounter with robbers, Chapter 0 explains why he was so protective of a small bundle he carried. This bundle contained powdered sugar, which he had with him because a saint named Janakidas Baba had advised him to feed sugar to ants. This detail highlights Kashiram's devotion and his practice of following the guidance of holy men. The bundle was so dear to him that he was willing to risk his life to protect it from the thieves.
