According to Chapter 22, why is the vision of Sai Baba's feet considered so important for his followers?

Chapter 22 places immense importance on the vision of the Guru's feet as the primary path to spiritual fulfillment. The text explicitly states that for devotees seeking "absolute fulfillment of happiness, there is no other path for us Except Your feet." It describes how numerous devotees would come for Baba's darshan, place their heads at his feet, and in doing so, "plunder personal happiness with love." This chapter of the Shri Sai Satcharitra reinforces this idea through the story of Baba showing a devotee the "moon of the nail" on his big toe, satisfying their longing for a vision. This, combined with the Das Ganu miracle, teaches that the Guru's feet are the sacred source of grace, blessings, and ultimate liberation.
