How did Maharaj's method of helping the sick evolve over time?

Initially, Maharaj actively practiced medicine, providing remedies to people without ever accepting money. Chapter 0 highlights his compassion by noting that he would personally care for patients if they were not being looked after properly. Later, he consciously shifted his approach; he stopped giving medicine and instead began distributing Udi, or ash, which people also found beneficial. Maharaj explained this transition to the author, 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."
