What details does Chapter 0 provide about Mhalasapati's background and his significance in Sai Baba's story?

Chapter 0 introduces Mhalasapati as a resident of Shirdi and a goldsmith by caste. He was a devout follower of Khandoba, and his family had a long tradition of visiting Khanderaya (Jejuri). His most significant contribution, as narrated in this chapter, was being the person who first addressed the Maharaj as "Sai Baba" upon his arrival at the Khandoba temple. This name, "Sai Baba," was adopted by the Maharaj and became the name he was known by for the rest of his life. Mhalasapati, along with his companions, became one of Baba's earliest and most devoted followers.
