How did Maharaj's method of healing people change over time after he arrived in Shirdi?

When Maharaj first arrived, his healing method involved conventional practices. As detailed in chapter 0, he would give medicine to people and never took money for it. He even personally nursed patients who were not being cared for properly. However, he later stopped this practice entirely. The text explicitly states that Maharaj stopped giving medicine and instead began to give only Udi, or sacred ash, which people found beneficial. He personally mentioned this transition to the author, confirming the shift from providing medicine to the spiritual practice of giving Udi.
