What miracle occurred when Das Ganu wanted to visit Prayag, according to the account in Chapter 22?

Chapter 22 recounts a powerful story involving Das Ganu's desire to go on a pilgrimage. When Das Ganu asked Sai Baba for permission to go bathe in the holy waters at Prayag, Baba instructed him not to go. Instead, Baba told him, 'Know this big toe of Mine to be Prayag; bathe right here.' Following his Guru's command, Das Ganu placed his head upon Baba's feet. At that very moment, a miracle unfolded. As the chapter vividly describes, the waters of both the sacred Ganga and Yamuna rivers manifested directly from Baba's big toe, allowing Das Ganu to have his holy bath right there in Shirdi, demonstrating the Sadguru's omnipresent power.
