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

Chapter 22 recounts a profound miracle that occurred when the devotee Das Ganu expressed his desire to travel to the holy site of Prayag for a sacred bath. When he asked for Sai Baba's permission, Baba instructed him that a pilgrimage was unnecessary. Baba told him, "Know this big toe of Mine to be Prayag; bathe right here." As detailed in Chapter 22, when the faithful Das Ganu placed his head on Baba's feet in obedience, the sacred waters of both the Ganga and Yamuna rivers miraculously manifested and flowed from Sai Baba's big toe. This event satisfied Das Ganu's desire and demonstrated that the Guru's feet are the holiest of all tirthas.
