What miracles or significant events are described in Chapter 22 of the Shri Sai Satcharitra?

Chapter 22 of the Shri Sai Satcharitra details a profound miracle involving the devotee Das Ganu. When Das Ganu expressed his desire to take a holy bath at the pilgrimage site of Prayag, Sai Baba instructed him that his own big toe was the true Prayag. As recounted in this chapter, when Das Ganu obediently placed his head on Baba's feet, the holy waters of both the Ganga and Yamuna rivers miraculously manifested from Baba's big toe, satisfying Das Ganu's spiritual longing without him needing to travel.
