How did Sai Baba ensure a constant supply of firewood for the sacred Dhuni that burned continuously in the Masjid?

The source material explains that Sai Baba's sacred fire, the Dhuni, burned twenty-four hours a day in the Masjid, regardless of the season. To maintain this, Baba had a strange determination. As detailed in Chapter 23, He would buy bundles of firewood purely for the sake of the Dhuni. He would pile this wood against the wall in the courtyard. Baba would specifically choose the time of the market to collect the wood. The text also notes that while Baba procured this wood, some selfish neighbors, both the needy and the deceitful, would take from His supply, which was made easier by the fact that the courtyard had no door.
