Describe the evolution of Maharaj's healing methods as explained to the author.

Maharaj's approach to healing people transformed over time. According to Chapter 0, he initially provided practical medical help. He would give people medicines free of charge and would even personally go and care for patients who were not being looked after properly. However, he later stopped this practice. Maharaj explained this shift to the author, whom he called 'Kaka,' stating that he stopped giving medicine and instead started chanting 'Hari Hari.' He then revealed the profound outcome of this change: "while saying Hari Hari, I met Hari." After this, he primarily gave Udi, or ash, to people who sought his help.
