According to the source text, what happened when Das Ganu wanted permission to go on a pilgrimage?

The story of Das Ganu in Chapter 22 provides a profound teaching on the nature of pilgrimage. When Das Ganu asked Sai Baba for permission to go and bathe in the holy waters at Prayag, Baba redirected his focus. Instead of granting permission for the journey, Baba stated that his own big toe was the real Prayag. He told Das Ganu to "bathe right here." Trusting his Guru, Das Ganu placed his head on Baba's feet. At that moment, as described in Chapter 22, the waters of both the Ganga and Yamuna rivers manifested right there from Baba's toe, satisfying Das Ganu's desire and teaching him that devotion to the Guru's feet is the highest form of pilgrimage.
