How does Chapter 22 detail the incident with Das Ganu and the significance of Sai Baba's feet?

Chapter 22 highlights the profound sanctity of Sai Baba's feet through the story of Das Ganu. When Das Ganu expressed a desire to go to Prayag to bathe in the holy confluence of the Ganga and Yamuna rivers, Baba told him it was unnecessary. As the chapter recounts, Baba instructed him, "Know this big toe of Mine to be Prayag; bathe right here." When a devoted Das Ganu placed his head on Baba's feet in acceptance, a miracle occurred. The text from Chapter 22 states that "both the waters of Ganga and Yamuna manifested right there at that spot" from Baba's big toe. This event powerfully demonstrates that the Sadguru's feet are the embodiment of all sacred tirthas and that true pilgrimage is found in surrender to the Guru.
