According to Chapter 22, what happened when Das Ganu wanted to visit Prayag for a holy bath?

The story of Das Ganu's request is a key miracle recounted in Chapter 22. When Das Ganu asked Sai Baba for permission to travel to the holy confluence of Prayag to bathe, Baba told him there was no need. Baba lovingly instructed him, "Know this big toe of Mine to be Prayag; bathe right here." Trusting his Guru's words, Das Ganu placed his head on Baba's feet. At that very moment, a miracle occurred: the holy waters of both the Ganga and Yamuna rivers manifested right there from Baba's big toe. This event, as described in the chapter, showed that the Guru's feet contained the sanctity of all holy places.
