What was the collective and individual significance of Mhalasapati, Kashiram Shimpi, and Appa Jagle in Sai Baba's early life in Shirdi, according to the introduction?

According to the introductory account in Chapter 0, these three men were pivotal figures. Mhalasapati, a goldsmith, was the first to welcome Maharaj and give him the name 'Sai Baba.' He then introduced Baba to his companions, Kashiram Shimpi and Appa Jagle. The trio, who were accustomed to serving holy men, became total devotees. Kashiram's devotion was particularly profound; he served Baba with his wealth, providing clothing, supplies for the chillum and Dhuni, and financial support. The text in Chapter 0 also notes the auspicious deaths of Kashiram and Appa, who both passed away on an Ekadashi day, highlighting their blessed status as devotees.
