What miracle did Maharaj perform for Chandbhai before coming to Shirdi?

The Introduction in Chapter 0 details a miracle Maharaj performed for Chandbhai in a forest. After Maharaj helped Chandbhai locate his lost horse, he prepared to smoke his chillum. However, there was no fire available in their location. To resolve this, Maharaj simply struck his tongs on the ground, which miraculously produced a fire, allowing him to proceed. This event impressed Chandbhai, who then insisted Maharaj come to his house, which eventually led to Maharaj traveling to Shirdi with Chandbhai's family.
