What is the spiritual meaning behind Sai Baba extinguishing the fire with his hand before leaving for the Chavadi?

Chapter 37 details the routine Sai Baba followed before the Chavadi procession. It mentions that He would go to a spot where firewood was kept, move His toe, and then extinguish the burning flame with His right hand before setting out. While this action is clearly described as a consistent part of His departure ritual, the provided excerpts do not explain the spiritual symbolism or theological reasoning behind it. The text focuses on describing the sequence of events rather than interpreting the deeper meaning of Baba's actions.
