Can you recount the story from Chapter 22 about Das Ganu and the holy rivers?

Chapter 22 narrates a profound miracle involving Das Ganu. When Das Ganu sought permission from Sai Baba to go bathe in the holy waters of Prayag, Baba instructed him that there was no need to travel. He declared, 'Know this big toe of Mine to be Prayag; bathe right here.' As soon as Das Ganu accepted this with faith and placed his head on Baba's feet, the holy waters of both the Ganga and Yamuna rivers manifested right there from Baba's big toe, satisfying Das Ganu's spiritual desire. This event, as mentioned in Chapter 22, demonstrates Baba's unfathomable power and inconceivable lila.
