What was Sai Baba's medical practice like when he first came to Shirdi, and how did it change over time?

When Maharaj first arrived in Shirdi, he actively practiced medicine, providing remedies to people completely free of charge. The introduction in Chapter 0 explains that if a patient wasn't being cared for properly, he would personally go and attend to them himself. However, he later stopped this practice. He mentioned to the author of the book that he transitioned from giving medicine to giving only Udi, or sacred ash, which also had healing properties. As Chapter 0 recounts, Maharaj told the writer, "I used to give medicine to people before. Later, I stopped giving medicine and started saying 'Hari Hari', and while saying Hari Hari, I met Hari."
