What is the significance of Sai Baba's feet as described in Chapter 22 of the Shri Sai Satcharitra?

In Chapter 22, Sai Baba's feet are depicted as the ultimate source of divine grace, knowledge, and fulfillment for devotees. The text explicitly states that for achieving absolute happiness, there is "no other path for us Except Your feet." This sanctity is illustrated through two powerful examples. Firstly, the nail of Baba's big toe is likened to the crescent moon, providing a divine vision to quench the spiritual longing of his followers. Secondly, the chapter recounts how the holy rivers Ganga and Yamuna flowed from his big toe for Das Ganu, transforming his feet into the sacred pilgrimage site of Prayag. These accounts from Chapter 22 firmly establish Baba's feet as the focal point of devotion and the embodiment of the divine itself.
