Can you explain the spiritual transition Maharaj described, from giving medicine to his later practices?

Chapter 0 provides insight into this shift through a conversation Maharaj had with a writer he called 'Kaka.' Maharaj explained, '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.' This statement suggests a deliberate evolution in his practice, moving from physical healing to a more direct path of devotion and God-realization through chanting. This change is also marked by his practice of giving Udi (ash) instead of medicine, a shift from the physical to the symbolic and spiritual.
