What miracle occurred when Das Ganu expressed his desire to visit Prayag for a holy bath, according to Chapter 22?

Chapter 22 narrates a significant miracle involving Das Ganu's desire for a holy pilgrimage. When Das Ganu asked Sai Baba for permission to go bathe in the holy waters at Prayag, Baba told him it was unnecessary. Instead, Baba proclaimed, 'Know this big toe of Mine to be Prayag; bathe right here.' As the chapter recounts, when Das Ganu trustingly placed his head on Baba's feet, a miracle unfolded. The waters of both the Ganga and Yamuna rivers manifested and flowed from Sai Baba's big toe at that very spot, fulfilling Das Ganu's wish in a profound and direct manner.
