What was the spiritual significance behind Maharaj stopping the practice of giving medicine and starting to give Udi instead?

The transition from giving medicine to giving Udi represents a profound shift in Maharaj's approach, as described in Chapter 0. He personally explained this change 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.' This suggests the shift was deeply spiritual. By moving from physical remedies to Udi and the constant remembrance of God's name, he guided devotees towards a deeper reliance on divine grace for both physical and spiritual well-being, illustrating that his ultimate goal was spiritual realization, or 'meeting Hari'.
