What does the incident with Nana Chandorkar at Thane station teach us about the nature of Udi and the power of faith?

The story of Nana Chandorkar at Thane station offers a profound insight into faith. According to Chapter 33, when a devotee urgently requested Udi for his sick daughter, Nana found himself without any. Rather than being helpless, he picked up ordinary clay from the road, offered a sincere prayer to Sai, and used it as a substitute. The fact that the girl's fever broke at that exact moment demonstrates that the healing power is not solely in the physical substance of Udi, but is activated by unwavering faith and prayer directed towards Sai. This event shows that with true devotion, even a particle of road clay can channel the same divine grace as the sacred ash from Shirdi.
