Can you describe the specific ritual Sai Baba performed with the fire before leaving the Masjid for the Chavadi procession?

Before departing for the Chavadi, Sai Baba would perform a distinct ritual. After Tatya Patil had helped Him prepare and placed a golden-bordered shawl over Him, Baba would approach a bundle of firewood kept against a wall. As detailed in Chapter 37, He would first move His right big toe at that spot for a moment. Then, He would personally wave His right hand over the burning flame that was there, extinguishing it completely before finally setting out for the procession.
