How did Maharaj's approach to healing people evolve over time?

Initially, Maharaj actively provided medical help to people by giving them medicines, for which he never accepted payment. Chapter 0 explains that he would even personally care for patients if they were not being looked after properly. However, he later ceased this practice. He transitioned from giving medicine to giving only Udi, or ash, which people also found beneficial. Maharaj explained this change to the writer, stating, "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."
