What happened when Das Ganu asked Sai Baba for permission to visit Prayag for a holy bath, as described in Chapter 22?

According to the account in Chapter 22, when Das Ganu sought permission to go bathe in the holy waters of Prayag, Sai Baba offered a profound alternative. Baba instructed him, "Know this big toe of Mine to be Prayag; bathe right here." The text states that when Das Ganu accepted this and placed his head upon Baba's feet, the sacred waters of both the Ganga and Yamuna rivers miraculously manifested right there at that spot. This event satisfied Das Ganu's spiritual desire and demonstrated the immense divine power present in the Sadguru's feet.
