According to Chapter 22, what miracle did Sai Baba perform for Das Ganu regarding a pilgrimage to Prayag?

Chapter 22 narrates a significant event involving Das Ganu. When Das Ganu sought Sai Baba's permission to go on a pilgrimage to bathe in the holy waters of Prayag, Baba instructed him otherwise. As recounted in Chapter 22, Baba told him, 'Know this big toe of Mine to be Prayag; bathe right here.' Trusting his Guru, Das Ganu placed his head upon Sai Baba's feet. At that very moment, a miracle occurred: the sacred waters of both the Ganga and Yamuna rivers manifested right there from Baba's big toe. This act demonstrated that the grace and presence of the Sadguru are holier than any pilgrimage site, satisfying Das Ganu's spiritual desire without him needing to travel.
