What happened when Das Ganu wanted to go to Prayag for a holy bath, according to Chapter 22?

Chapter 22 narrates a profound incident involving Das Ganu. When he expressed his desire to go on a pilgrimage to Prayag to bathe in the holy confluence of the Ganga and Yamuna, Sai Baba stopped him. Baba declared that the journey was unnecessary, stating, 'Know this big toe of Mine to be Prayag; bathe right here.' Trusting his Guru's words, Das Ganu placed his head reverently upon Baba's feet. At that very moment, a miracle occurred: the sacred waters of both the Ganga and Yamuna rivers began to flow from Baba's big toe. This story from Chapter 22 powerfully illustrates the teaching that the Sadguru's feet are the ultimate pilgrimage site.
