How did Sai Baba's method of healing people change over time when he first came to Shirdi?

Initially, when Maharaj first resided in the dilapidated Masjid in Shirdi, he would actively give medicines to people who were sick. As detailed in Chapter 0, he never took money for his services and would even personally care for patients who were not being looked after properly. However, he later stopped this practice. He told the author, whom he called Kaka, that he stopped giving medicine and instead started giving Udi, or sacred ash. He explained that he then focused on chanting 'Hari Hari', and through this, he 'met Hari'. This shift from physical medicine to spiritual remedies marks a significant evolution in his early ministry.
