What miraculous event involving Das Ganu and Sai Baba's big toe is recounted in Chapter 22?

Chapter 22 narrates a specific incident concerning the devotee Das Ganu. When Das Ganu asked for permission to go on a pilgrimage to bathe in the holy waters of Prayag, Sai Baba instructed him otherwise. Baba told him, 'Know this big toe of Mine to be Prayag; bathe right here.' As the text recounts, when Das Ganu followed this command and placed his head on Baba's feet, the waters of both the Ganga and Yamuna rivers miraculously manifested from that very spot. This event satisfied Das Ganu's desire for a holy bath without him ever needing to travel.
