I heard Sai Baba pointed out a significant tomb. What is the story behind that discovery?

Yes, Chapter 0 recounts how Maharaj paid attention not only to village temples but also to a tomb, or 'Turbat'. Maharaj sometimes sat under a Neem tree near the village boundary and once declared that a Pir's tomb was located there. When the spot was excavated, a tomb was indeed found. This discovery led the people to hold a procession with music in Maharaj's honor. Maharaj himself referred to this tomb, telling the writer, "This is our father's place. Burn incense here every Thursday and Friday; that will be for your own welfare," indicating its deep spiritual significance.
