How did Maharaj's method of healing people evolve over time?

Maharaj's approach to healing underwent a significant transformation. Initially, as described in Chapter 0, he would give medicines to people, never charging any money for them. He was so dedicated that if a patient was not being cared for properly, he would go and personally tend to them himself. Later, he stopped this practice of giving medicine. Instead, he began to give only Udi, or sacred ash, which people also found beneficial. Maharaj explained this shift by telling the author, "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."
