Chapter 22 places a lot of significance on Sai Baba's feet and big toe. What is the symbolism behind this?

The focus on Sai Baba's feet and big toe in Chapter 22 is rich with symbolism. The chapter explicitly states that the Guru's feet are the only path to achieving "absolute fulfillment of happiness." It describes a specific posture where Baba's right foot is over his left knee, and the nail of his big toe shines like the crescent moon after a new moon night. This fulfilled the devotees' longing for a divine vision. The symbolism culminates in the story of Das Ganu, where, as Chapter 22 explains, Baba declares his big toe to be the holy confluence of Prayag. The subsequent manifestation of the Ganga and Yamuna from his toe demonstrates that the Guru's feet are not just a path to divinity but are the embodiment of divinity itself.
