Before arriving in Shirdi, Maharaj performed a miracle for Chandbhai. What was this event and how did it happen?

The introductory section of Chapter 0 describes a miraculous event that occurred while Maharaj was with Chandbhai in a forest. After Maharaj helped Chandbhai locate his lost horse, he needed a fire for his chillum. Since there was no fire readily available in their location, Maharaj performed a wondrous act. The text states that Maharaj simply "struck his tongs on the ground, produced fire, and finished his task." This display of supernatural ability took place before he accompanied Chandbhai's family to Shirdi for a wedding.
