How did the saint who became known as Sai Baba first arrive in Shirdi, and what were the circumstances that led to him being called by that name?

According to Chapter 0, the figure who would become Sai Baba arrived in Shirdi as part of a wedding procession for Chandbhai's wife's nephew. The text explains that the procession stopped in a garden near the Khandoba temple. Upon entering the temple, he met a resident named Mhalasapati who, upon seeing him, greeted him with the words "Aavo Sai Baba" (Come, Sai Baba). As Chapter 0 states, Maharaj held that name until the end, even confirming in a later testimony that "They call me Sai Baba."
