How did Sai Baba's approach to healing people change over time?

Initially, when Maharaj first arrived in Shirdi, he was known for providing medical care to people. As detailed in Chapter 0, he gave out medicines free of charge and would even personally nurse patients who were not being cared for properly. However, this practice eventually ceased. Maharaj explained to the author, whom he called "Kaka," that he later stopped giving medicine and instead began to give only Udi, or sacred ash. This ash also proved to be beneficial for people, marking a significant shift in his method of healing from physical remedies to spiritual blessings.
