How did Sai Baba's appearance change during the Chavadi procession, and what significant actions did he perform?

During the Chavadi procession, Sai Baba's appearance was described as particularly radiant. Chapter 51 notes that his face, already having a golden hue, would shine like 'gold mixed with copper' or the morning sun when illuminated by the lamps and torches held by devotees. A significant moment occurred when the procession came before the Chavadi. Baba would stop, face north with a focused mind, and perform ritual hand movements. This action was so distinct that it seemed as though He was calling someone, moving His right hand up and down. During this part of the procession, Tatya Patil would walk on Baba's left side holding a lantern, further contributing to the divine glow surrounding him.
