According to Chapter 22, what is the significance of Baba's feet and what miraculous event involving Das Ganu is described?

Chapter 22 places immense importance on the Sadguru's feet, calling them the only path to achieving "absolute fulfillment of happiness." It describes how devotees would place their heads at His feet to find joy. The chapter highlights this sanctity with the story of Das Ganu, who wanted permission to go to Prayag for a holy bath. Baba instructed him, "Know this big toe of Mine to be Prayag; bathe right here." As Chapter 22 recounts, when Das Ganu placed his head on Baba's feet in obedience, the waters of the sacred Ganga and Yamuna rivers miraculously manifested from Baba's big toe, fulfilling Das Ganu's desire and proving the divine power residing in the Guru's feet.
