Can you describe the roles of Mhalasapati, Kashiram Shimpi, and Appa Jagle in serving Sai Baba and other holy men?

Chapter 0 details the significant roles of Mhalasapati, Kashiram Shimpi, and Appa Jagle. After Mhalasapati met Maharaj, he introduced him to his companions, Kashiram and Appa. The three of them had a practice of serving and looking after saints, Gosavis, Bairagis, and Fakirs who visited the busy village of Shirdi, providing hospitality according to their means. The text states that all three became total devotees of Maharaj. Kashiram, in particular, served Maharaj with his body, mind, and wealth, even vowing to provide for his needs.
