What miracle involving Das Ganu and the holy rivers is described in Chapter 22?

Chapter 22 recounts a significant miracle that occurred when Das Ganu wished to go on a pilgrimage to Prayag for a holy bath. When he asked for permission, Sai Baba told him, "Know this big toe of Mine to be Prayag; bathe right here." As detailed in this chapter of the Shri Sai Satcharitra, when the obedient Das Ganu placed his head upon Sai Baba's feet, he was astonished to see the waters of both the Ganga and Yamuna rivers manifest and flow directly from Baba's big toe. This miraculous event satisfied Das Ganu's desire for a sacred bath and demonstrated the profound truth that the Guru's feet are the ultimate and most sacred pilgrimage destination.
