How did Maharaj's approach to healing people in Shirdi change over time?

According to the introduction in Chapter 0, Maharaj's methods for helping people evolved significantly. Initially, he actively provided medicine to the sick and would never accept money for his services. His compassion was so great that if a patient was not being cared for properly, he would personally go and nurse them. However, he later ceased this practice. The text explains that Maharaj stopped giving medicine and instead began to give only Udi, or sacred ash, which people also found beneficial. Maharaj himself commented on this shift, telling 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."
