Before he was known as Sai Baba of Shirdi, what miraculous event involving fire is described in Chapter 0 during his time with Chandbhai?

The introduction in Chapter 0 recounts a miraculous incident that occurred before Maharaj came to Shirdi. While staying with Chandbhai, Maharaj needed a fire to light his chillum. They were in a forest where no fire was available. To solve this, Maharaj simply struck his tongs on the ground, and from that spot, he miraculously produced fire to complete his task. This event, which happened after he had already helped Chandbhai find his lost horse, demonstrated his divine powers to Chandbhai even before his arrival and fame in Shirdi.
