How did Sai Baba appear and what specific actions did he perform during a key moment of the Chavadi procession?

During the procession, Sai Baba's appearance was described as magnificent. Chapter 51 explains that his face, already having a golden hue, would shine like 'gold mixed with copper, like the morning sun' when illuminated by the lamplight. A key moment occurred when the procession came before the Chavadi. Baba would stop and stand facing north. With a focused mind, he would perform ritual hand movements, moving his right hand up and down as if he were calling someone. This act was considered a holy and blessed darshan for all who witnessed it, after which he would be escorted into the Chavadi.
